+How to make RPMs of the wxWindows sources
+=========================================
+
+This is just a short description. It is assumed that you know what you are
+doing. I do not take any responsibility for damaged systems, use at your own
+risk!
+
+	1. Extract the archive in a temporary directory. Since you are
+	   reading this text, you already have done this.
+	2. Copy the .spec file to
+		(rpm-dir)/SPECS
+	3. Copy the .tgz file to
+		(rpm-dir)/SOURCES
+	4. Start the RPM manager with
+		rpm -bb (rpm-dir)/SPECS/(.spec-file)
+	   or with
+		rpm -ba (rpm-dir)/SPECS/(.spec-file)
+	   (the latter also builds the .src.rpm-file)
+	5. You now have a nice set of RPMs in (rpm-dir)/RPMS
+
+Example
+=======
+
+Here's how to install e.g. wxMotif 2.1.14:
+
+	cp wxMotif.spec /usr/src/packages/SPECS
+	cp wxMotif-2.1.14.tgz /usr/src/packages/SOURCES
+	rpm -bb /usr/src/packages/SPECS/wxMotif.spec
+
+Install the resulting packages with
+
+	rpm --install /usr/src/packages/RPMS/i386/wxMotif-2.1.14-0.i386.rpm
+	rpm --install /usr/src/packages/RPMS/i386/wxMotif-devel-2.1.14-0.i386.rpm
+	rpm --install /usr/src/packages/RPMS/i386/wxMotif-gl-2.1.14-0.i386.rpm
+
+
+
+That's all. You should now have a working wxWindows library.
+
+Regards,
+	Robert Fendt

-.SH NAME
-re_syntax \- Syntax of Tcl regular expressions.
-.BE
-
-.SH DESCRIPTION
-.PP
-A \fIregular expression\fR describes strings of characters.
-It's a pattern that matches certain strings and doesn't match others.
-
-.SH "DIFFERENT FLAVORS OF REs"
-Regular expressions (``RE''s), as defined by POSIX, come in two
-flavors: \fIextended\fR REs (``EREs'') and \fIbasic\fR REs (``BREs'').
-EREs are roughly those of the traditional \fIegrep\fR, while BREs are
-roughly those of the traditional \fIed\fR.  This implementation adds
-a third flavor, \fIadvanced\fR REs (``AREs''), basically EREs with
-some significant extensions.
-.PP
-This manual page primarily describes AREs.  BREs mostly exist for
-backward compatibility in some old programs; they will be discussed at
-the end.  POSIX EREs are almost an exact subset of AREs.  Features of
-AREs that are not present in EREs will be indicated.
-
-.SH "REGULAR EXPRESSION SYNTAX"
-.PP
-Tcl regular expressions are implemented using the package written by
-Henry Spencer, based on the 1003.2 spec and some (not quite all) of
-the Perl5 extensions (thanks, Henry!).  Much of the description of
-regular expressions below is copied verbatim from his manual entry.
-.PP
-An ARE is one or more \fIbranches\fR,
-separated by `\fB|\fR',
-matching anything that matches any of the branches.
-.PP
-A branch is zero or more \fIconstraints\fR or \fIquantified atoms\fR,
-concatenated.
-It matches a match for the first, followed by a match for the second, etc;
-an empty branch matches the empty string.
-.PP
-A quantified atom is an \fIatom\fR possibly followed
-by a single \fIquantifier\fR.
-Without a quantifier, it matches a match for the atom.
-The quantifiers,
-and what a so-quantified atom matches, are:
-.RS 2
-.TP 6
-\fB*\fR
-a sequence of 0 or more matches of the atom
-.TP
-\fB+\fR
-a sequence of 1 or more matches of the atom
-.TP
-\fB?\fR
-a sequence of 0 or 1 matches of the atom
-.TP
-\fB{\fIm\fB}\fR
-a sequence of exactly \fIm\fR matches of the atom
-.TP
-\fB{\fIm\fB,}\fR
-a sequence of \fIm\fR or more matches of the atom
-.TP
-\fB{\fIm\fB,\fIn\fB}\fR
-a sequence of \fIm\fR through \fIn\fR (inclusive) matches of the atom;
-\fIm\fR may not exceed \fIn\fR
-.TP
-\fB*?  +?  ??  {\fIm\fB}?  {\fIm\fB,}?  {\fIm\fB,\fIn\fB}?\fR
-\fInon-greedy\fR quantifiers,
-which match the same possibilities,
-but prefer the smallest number rather than the largest number
-of matches (see MATCHING)
-.RE
-.PP
-The forms using
-\fB{\fR and \fB}\fR
-are known as \fIbound\fRs.
-The numbers
-\fIm\fR and \fIn\fR are unsigned decimal integers
-with permissible values from 0 to 255 inclusive.
-.PP
-An atom is one of:
-.RS 2
-.TP 6
-\fB(\fIre\fB)\fR
-(where \fIre\fR is any regular expression)
-matches a match for
-\fIre\fR, with the match noted for possible reporting
-.TP
-\fB(?:\fIre\fB)\fR
-as previous,
-but does no reporting
-(a ``non-capturing'' set of parentheses)
-.TP
-\fB()\fR
-matches an empty string,
-noted for possible reporting
-.TP
-\fB(?:)\fR
-matches an empty string,
-without reporting
-.TP
-\fB[\fIchars\fB]\fR
-a \fIbracket expression\fR,
-matching any one of the \fIchars\fR (see BRACKET EXPRESSIONS for more detail)
-.TP
- \fB.\fR
-matches any single character
-.TP
-\fB\e\fIk\fR
-(where \fIk\fR is a non-alphanumeric character)
-matches that character taken as an ordinary character,
-e.g. \e\e matches a backslash character
-.TP
-\fB\e\fIc\fR
-where \fIc\fR is alphanumeric
-(possibly followed by other characters),
-an \fIescape\fR (AREs only),
-see ESCAPES below
-.TP
-\fB{\fR
-when followed by a character other than a digit,
-matches the left-brace character `\fB{\fR';
-when followed by a digit, it is the beginning of a
-\fIbound\fR (see above)
-.TP
-\fIx\fR
-where \fIx\fR is
-a single character with no other significance, matches that character.
-.RE
-.PP
-A \fIconstraint\fR matches an empty string when specific conditions
-are met.
-A constraint may not be followed by a quantifier.
-The simple constraints are as follows; some more constraints are
-described later, under ESCAPES.
-.RS 2
-.TP 8
-\fB^\fR
-matches at the beginning of a line
-.TP
-\fB$\fR
-matches at the end of a line
-.TP
-\fB(?=\fIre\fB)\fR
-\fIpositive lookahead\fR (AREs only), matches at any point
-where a substring matching \fIre\fR begins
-.TP
-\fB(?!\fIre\fB)\fR
-\fInegative lookahead\fR (AREs only), matches at any point
-where no substring matching \fIre\fR begins
-.RE
-.PP
-The lookahead constraints may not contain back references (see later),
-and all parentheses within them are considered non-capturing.
-.PP
-An RE may not end with `\fB\e\fR'.
-
-.SH "BRACKET EXPRESSIONS"
-A \fIbracket expression\fR is a list of characters enclosed in `\fB[\|]\fR'.
-It normally matches any single character from the list (but see below).
-If the list begins with `\fB^\fR',
-it matches any single character
-(but see below) \fInot\fR from the rest of the list.
-.PP
-If two characters in the list are separated by `\fB\-\fR',
-this is shorthand
-for the full \fIrange\fR of characters between those two (inclusive) in the
-collating sequence,
-e.g.
-\fB[0\-9]\fR
-in ASCII matches any decimal digit.
-Two ranges may not share an
-endpoint, so e.g.
-\fBa\-c\-e\fR
-is illegal.
-Ranges are very collating-sequence-dependent,
-and portable programs should avoid relying on them.
-.PP
-To include a literal
-\fB]\fR
-or
-\fB\-\fR
-in the list,
-the simplest method is to
-enclose it in
-\fB[.\fR and \fB.]\fR
-to make it a collating element (see below).
-Alternatively,
-make it the first character
-(following a possible `\fB^\fR'),
-or (AREs only) precede it with `\fB\e\fR'.
-Alternatively, for `\fB\-\fR',
-make it the last character,
-or the second endpoint of a range.
-To use a literal
-\fB\-\fR
-as the first endpoint of a range,
-make it a collating element
-or (AREs only) precede it with `\fB\e\fR'.
-With the exception of these, some combinations using
-\fB[\fR
-(see next
-paragraphs), and escapes,
-all other special characters lose their
-special significance within a bracket expression.
-.PP
-Within a bracket expression, a collating element (a character,
-a multi-character sequence that collates as if it were a single character,
-or a collating-sequence name for either)
-enclosed in
-\fB[.\fR and \fB.]\fR
-stands for the
-sequence of characters of that collating element.
-The sequence is a single element of the bracket expression's list.
-A bracket expression in a locale that has
-multi-character collating elements
-can thus match more than one character.
-.VS 8.2
-So (insidiously), a bracket expression that starts with \fB^\fR
-can match multi-character collating elements even if none of them
-appear in the bracket expression!
-(\fINote:\fR Tcl currently has no multi-character collating elements.
-This information is only for illustration.)
-.PP
-For example, assume the collating sequence includes a \fBch\fR
-multi-character collating element.
-Then the RE \fB[[.ch.]]*c\fR (zero or more \fBch\fP's followed by \fBc\fP)
-matches the first five characters of `\fBchchcc\fR'.
-Also, the RE \fB[^c]b\fR matches all of `\fBchb\fR'
-(because \fB[^c]\fR matches the multi-character \fBch\fR).
-.VE 8.2
-.PP
-Within a bracket expression, a collating element enclosed in
-\fB[=\fR
-and
-\fB=]\fR
-is an equivalence class, standing for the sequences of characters
-of all collating elements equivalent to that one, including itself.
-(If there are no other equivalent collating elements,
-the treatment is as if the enclosing delimiters were `\fB[.\fR'\&
-and `\fB.]\fR'.)
-For example, if
-\fBo\fR
-and
-\fB\o'o^'\fR
-are the members of an equivalence class,
-then `\fB[[=o=]]\fR', `\fB[[=\o'o^'=]]\fR',
-and `\fB[o\o'o^']\fR'\&
-are all synonymous.
-An equivalence class may not be an endpoint
-of a range.
-.VS 8.2
-(\fINote:\fR 
-Tcl currently implements only the Unicode locale.
-It doesn't define any equivalence classes.
-The examples above are just illustrations.)
-.VE 8.2
-.PP
-Within a bracket expression, the name of a \fIcharacter class\fR enclosed
-in
-\fB[:\fR
-and
-\fB:]\fR
-stands for the list of all characters
-(not all collating elements!)
-belonging to that
-class.
-Standard character classes are:
-.PP
-.RS
-.ne 5
-.nf
-.ta 3c
-\fBalpha\fR	A letter. 
-\fBupper\fR	An upper-case letter. 
-\fBlower\fR	A lower-case letter. 
-\fBdigit\fR	A decimal digit. 
-\fBxdigit\fR	A hexadecimal digit. 
-\fBalnum\fR	An alphanumeric (letter or digit). 
-\fBprint\fR	An alphanumeric (same as alnum).
-\fBblank\fR	A space or tab character.
-\fBspace\fR	A character producing white space in displayed text. 
-\fBpunct\fR	A punctuation character. 
-\fBgraph\fR	A character with a visible representation. 
-\fBcntrl\fR	A control character. 
-.fi
-.RE
-.PP
-A locale may provide others.

-.SH ESCAPES
-Escapes (AREs only), which begin with a
-\fB\e\fR
-followed by an alphanumeric character,
-come in several varieties:
-character entry, class shorthands, constraint escapes, and back references.
-A
-\fB\e\fR
-followed by an alphanumeric character but not constituting
-a valid escape is illegal in AREs.
-In EREs, there are no escapes:
-outside a bracket expression,
-a
-\fB\e\fR
-followed by an alphanumeric character merely stands for that
-character as an ordinary character,
-and inside a bracket expression,
-\fB\e\fR
-is an ordinary character.
-(The latter is the one actual incompatibility between EREs and AREs.)
-.PP
-Character-entry escapes (AREs only) exist to make it easier to specify
-non-printing and otherwise inconvenient characters in REs:
-.RS 2
-.TP 5
-\fB\ea\fR
-alert (bell) character, as in C
-.TP
-\fB\eb\fR
-backspace, as in C
-.TP
-\fB\eB\fR

-.RE
-.PP
-Hexadecimal digits are `\fB0\fR'-`\fB9\fR', `\fBa\fR'-`\fBf\fR',
-and `\fBA\fR'-`\fBF\fR'.
-Octal digits are `\fB0\fR'-`\fB7\fR'.
-.PP
-The character-entry escapes are always taken as ordinary characters.
-For example,
-\fB\e135\fR
-is
-\fB]\fR
-in ASCII,
-but
-\fB\e135\fR
-does not terminate a bracket expression.
-Beware, however, that some applications (e.g., C compilers) interpret 
-such sequences themselves before the regular-expression package
-gets to see them, which may require doubling (quadrupling, etc.) the `\fB\e\fR'.
-.PP
-Class-shorthand escapes (AREs only) provide shorthands for certain commonly-used
-character classes:
-.RS 2
-.TP 10
-\fB\ed\fR
-\fB[[:digit:]]\fR

-\fB\es\fR
-\fB[[:space:]]\fR
-.TP
-\fB\ew\fR

-\fB[^[:alnum:]_]\fR
-(note underscore)
-.RE
-.PP
-Within bracket expressions, `\fB\ed\fR', `\fB\es\fR',
-and `\fB\ew\fR'\&
-lose their outer brackets,
-and `\fB\eD\fR', `\fB\eS\fR',
-and `\fB\eW\fR'\&
-are illegal.
-.VS 8.2
-(So, for example, \fB[a-c\ed]\fR is equivalent to \fB[a-c[:digit:]]\fR.
-Also, \fB[a-c\eD]\fR, which is equivalent to \fB[a-c^[:digit:]]\fR, is illegal.)
-.VE 8.2
-.PP
-A constraint escape (AREs only) is a constraint,
-matching the empty string if specific conditions are met,
-written as an escape:

-(see MATCHING, below, for how this differs from `\fB^\fR')
-.TP
-\fB\em\fR

-a \fIback reference\fR, see below
-.RE
-.PP
-A word is defined as in the specification of
-\fB[[:<:]]\fR
-and
-\fB[[:>:]]\fR
-above.
-Constraint escapes are illegal within bracket expressions.
-.PP
-A back reference (AREs only) matches the same string matched by the parenthesized
-subexpression specified by the number,
-so that (e.g.)
-\fB([bc])\e1\fR
-matches
-\fBbb\fR
-or
-\fBcc\fR
-but not `\fBbc\fR'.
-The subexpression must entirely precede the back reference in the RE.
-Subexpressions are numbered in the order of their leading parentheses.
-Non-capturing parentheses do not define subexpressions.
-.PP
-There is an inherent historical ambiguity between octal character-entry 
-escapes and back references, which is resolved by heuristics,
-as hinted at above.
-A leading zero always indicates an octal escape.
-A single non-zero digit, not followed by another digit,
-is always taken as a back reference.
-A multi-digit sequence not starting with a zero is taken as a back 
-reference if it comes after a suitable subexpression
-(i.e. the number is in the legal range for a back reference),
-and otherwise is taken as octal.
-.SH "METASYNTAX"
-In addition to the main syntax described above, there are some special
-forms and miscellaneous syntactic facilities available.
-.PP
-Normally the flavor of RE being used is specified by
-application-dependent means.
-However, this can be overridden by a \fIdirector\fR.
-If an RE of any flavor begins with `\fB***:\fR',
-the rest of the RE is an ARE.
-If an RE of any flavor begins with `\fB***=\fR',
-the rest of the RE is taken to be a literal string,
-with all characters considered ordinary characters.
-.PP
-An ARE may begin with \fIembedded options\fR:
-a sequence
-\fB(?\fIxyz\fB)\fR
-(where
-\fIxyz\fR
-is one or more alphabetic characters)
-specifies options affecting the rest of the RE.
-These supplement, and can override,
-any options specified by the application.
-The available option letters are:
-.RS 2
-.TP 3
-\fBb\fR
-rest of RE is a BRE
-.TP 3
-\fBc\fR
-case-sensitive matching (usual default)
-.TP 3
-\fBe\fR
-rest of RE is an ERE
-.TP 3
-\fBi\fR
-case-insensitive matching (see MATCHING, below)
-.TP 3
-\fBm\fR
-historical synonym for
-\fBn\fR
-.TP 3
-\fBn\fR
-newline-sensitive matching (see MATCHING, below)
-.TP 3
-\fBp\fR
-partial newline-sensitive matching (see MATCHING, below)
-.TP 3
-\fBq\fR
-rest of RE is a literal (``quoted'') string, all ordinary characters
-.TP 3
-\fBs\fR
-non-newline-sensitive matching (usual default)
-.TP 3
-\fBt\fR
-tight syntax (usual default; see below)
-.TP 3
-\fBw\fR
-inverse partial newline-sensitive (``weird'') matching (see MATCHING, below)
-.TP 3
-\fBx\fR
-expanded syntax (see below)
-.RE
-.PP
-Embedded options take effect at the
-\fB)\fR
-terminating the sequence.
-They are available only at the start of an ARE,
-and may not be used later within it.
-.PP
-In addition to the usual (\fItight\fR) RE syntax, in which all characters are
-significant, there is an \fIexpanded\fR syntax,
-available in all flavors of RE
-with the \fB-expanded\fR switch, or in AREs with the embedded x option.
-In the expanded syntax,
-white-space characters are ignored
-and all characters between a
-\fB#\fR
-and the following newline (or the end of the RE) are ignored,
-permitting paragraphing and commenting a complex RE.
-There are three exceptions to that basic rule:
-.RS 2
-.PP
-a white-space character or `\fB#\fR' preceded by `\fB\e\fR' is retained
-.PP
-white space or `\fB#\fR' within a bracket expression is retained
-.PP
-white space and comments are illegal within multi-character symbols
-like the ARE `\fB(?:\fR' or the BRE `\fB\e(\fR'
-.RE
-.PP
-Expanded-syntax white-space characters are blank, tab, newline, and
-.VS 8.2
-any character that belongs to the \fIspace\fR character class.
-.VE 8.2
-.PP
-Finally, in an ARE,
-outside bracket expressions, the sequence `\fB(?#\fIttt\fB)\fR'
-(where
-\fIttt\fR
-is any text not containing a `\fB)\fR')
-is a comment,
-completely ignored.
-Again, this is not allowed between the characters of
-multi-character symbols like `\fB(?:\fR'.
-Such comments are more a historical artifact than a useful facility,
-and their use is deprecated;
-use the expanded syntax instead.
-.PP
-\fINone\fR of these metasyntax extensions is available if the application
-(or an initial
-\fB***=\fR
-director)
-has specified that the user's input be treated as a literal string
-rather than as an RE.
-.SH MATCHING
-In the event that an RE could match more than one substring of a given
-string,
-the RE matches the one starting earliest in the string.
-If the RE could match more than one substring starting at that point,
-its choice is determined by its \fIpreference\fR:
-either the longest substring, or the shortest.
-.PP
-Most atoms, and all constraints, have no preference.
-A parenthesized RE has the same preference (possibly none) as the RE.
-A quantified atom with quantifier
-\fB{\fIm\fB}\fR
-or
-\fB{\fIm\fB}?\fR
-has the same preference (possibly none) as the atom itself.
-A quantified atom with other normal quantifiers (including
-\fB{\fIm\fB,\fIn\fB}\fR
-with
-\fIm\fR
-equal to
-\fIn\fR)
-prefers longest match.
-A quantified atom with other non-greedy quantifiers (including
-\fB{\fIm\fB,\fIn\fB}?\fR
-with
-\fIm\fR
-equal to
-\fIn\fR)
-prefers shortest match.
-A branch has the same preference as the first quantified atom in it
-which has a preference.
-An RE consisting of two or more branches connected by the
-\fB|\fR
-operator prefers longest match.
-.PP
-Subject to the constraints imposed by the rules for matching the whole RE,
-subexpressions also match the longest or shortest possible substrings,
-based on their preferences,
-with subexpressions starting earlier in the RE taking priority over
-ones starting later.
-Note that outer subexpressions thus take priority over
-their component subexpressions.
-.PP
-Note that the quantifiers
-\fB{1,1}\fR
-and
-\fB{1,1}?\fR
-can be used to force longest and shortest preference, respectively,
-on a subexpression or a whole RE.
-.PP
-Match lengths are measured in characters, not collating elements.
-An empty string is considered longer than no match at all.
-For example,
-\fBbb*\fR
-matches the three middle characters of `\fBabbbc\fR',
-\fB(week|wee)(night|knights)\fR
-matches all ten characters of `\fBweeknights\fR',
-when
-\fB(.*).*\fR
-is matched against
-\fBabc\fR
-the parenthesized subexpression
-matches all three characters, and
-when
-\fB(a*)*\fR
-is matched against
-\fBbc\fR
-both the whole RE and the parenthesized
-subexpression match an empty string.
-.PP
-If case-independent matching is specified,
-the effect is much as if all case distinctions had vanished from the
-alphabet.
-When an alphabetic that exists in multiple cases appears as an
-ordinary character outside a bracket expression, it is effectively
-transformed into a bracket expression containing both cases,
-so that
-\fBx\fR
-becomes `\fB[xX]\fR'.
-When it appears inside a bracket expression, all case counterparts
-of it are added to the bracket expression, so that
-\fB[x]\fR
-becomes
-\fB[xX]\fR
-and
-\fB[^x]\fR
-becomes `\fB[^xX]\fR'.
-.PP
-If newline-sensitive matching is specified, \fB.\fR
-and bracket expressions using
-\fB^\fR
-will never match the newline character
-(so that matches will never cross newlines unless the RE
-explicitly arranges it)
-and
-\fB^\fR
-and
-\fB$\fR
-will match the empty string after and before a newline
-respectively, in addition to matching at beginning and end of string
-respectively.
-ARE
-\fB\eA\fR
-and
-\fB\eZ\fR
-continue to match beginning or end of string \fIonly\fR.
-.PP
-If partial newline-sensitive matching is specified,
-this affects \fB.\fR
-and bracket expressions
-as with newline-sensitive matching, but not
-\fB^\fR
-and `\fB$\fR'.
-.PP
-If inverse partial newline-sensitive matching is specified,
-this affects
-\fB^\fR
-and
-\fB$\fR
-as with
-newline-sensitive matching,
-but not \fB.\fR
-and bracket expressions.
-This isn't very useful but is provided for symmetry.
-.SH "LIMITS AND COMPATIBILITY"
-No particular limit is imposed on the length of REs.
-Programs intended to be highly portable should not employ REs longer
-than 256 bytes,
-as a POSIX-compliant implementation can refuse to accept such REs.
-.PP
-The only feature of AREs that is actually incompatible with
-POSIX EREs is that
-\fB\e\fR
-does not lose its special
-significance inside bracket expressions.
-All other ARE features use syntax which is illegal or has
-undefined or unspecified effects in POSIX EREs;
-the
-\fB***\fR
-syntax of directors likewise is outside the POSIX
-syntax for both BREs and EREs.
-.PP
-Many of the ARE extensions are borrowed from Perl, but some have
-been changed to clean them up, and a few Perl extensions are not present.
-Incompatibilities of note include `\fB\eb\fR', `\fB\eB\fR',
-the lack of special treatment for a trailing newline,
-the addition of complemented bracket expressions to the things
-affected by newline-sensitive matching,
-the restrictions on parentheses and back references in lookahead constraints,
-and the longest/shortest-match (rather than first-match) matching semantics.
-.PP
-The matching rules for REs containing both normal and non-greedy quantifiers
-have changed since early beta-test versions of this package.
-(The new rules are much simpler and cleaner,
-but don't work as hard at guessing the user's real intentions.)
-.PP
-Henry Spencer's original 1986 \fIregexp\fR package,
-still in widespread use (e.g., in pre-8.1 releases of Tcl),
-implemented an early version of today's EREs.
-There are four incompatibilities between \fIregexp\fR's near-EREs
-(`RREs' for short) and AREs.
-In roughly increasing order of significance:
-.PP
-.RS
-In AREs,
-\fB\e\fR
-followed by an alphanumeric character is either an
-escape or an error,
-while in RREs, it was just another way of writing the 
-alphanumeric.
-This should not be a problem because there was no reason to write
-such a sequence in RREs.
-.PP
-\fB{\fR
-followed by a digit in an ARE is the beginning of a bound,
-while in RREs,
-\fB{\fR
-was always an ordinary character.
-Such sequences should be rare,
-and will often result in an error because following characters
-will not look like a valid bound.
-.PP
-In AREs,
-\fB\e\fR
-remains a special character within `\fB[\|]\fR',
-so a literal
-\fB\e\fR
-within
-\fB[\|]\fR
-must be written `\fB\e\e\fR'.
-\fB\e\e\fR
-also gives a literal
-\fB\e\fR
-within
-\fB[\|]\fR
-in RREs,
-but only truly paranoid programmers routinely doubled the backslash.
-.PP
-AREs report the longest/shortest match for the RE,
-rather than the first found in a specified search order.
-This may affect some RREs which were written in the expectation that
-the first match would be reported.
-(The careful crafting of RREs to optimize the search order for fast
-matching is obsolete (AREs examine all possible matches
-in parallel, and their performance is largely insensitive to their
-complexity) but cases where the search order was exploited to deliberately 
-find a match which was \fInot\fR the longest/shortest will need rewriting.)
-.RE
-
-.SH "BASIC REGULAR EXPRESSIONS"
-BREs differ from EREs in several respects.  `\fB|\fR', `\fB+\fR',
-and
-\fB?\fR
-are ordinary characters and there is no equivalent
-for their functionality.
-The delimiters for bounds are
-\fB\e{\fR
-and `\fB\e}\fR',
-with
-\fB{\fR
-and
-\fB}\fR
-by themselves ordinary characters.
-The parentheses for nested subexpressions are
-\fB\e(\fR
-and `\fB\e)\fR',
-with
-\fB(\fR
-and
-\fB)\fR
-by themselves ordinary characters.
-\fB^\fR
-is an ordinary character except at the beginning of the
-RE or the beginning of a parenthesized subexpression,
-\fB$\fR
-is an ordinary character except at the end of the
-RE or the end of a parenthesized subexpression,
-and
-\fB*\fR
-is an ordinary character if it appears at the beginning of the
-RE or the beginning of a parenthesized subexpression
-(after a possible leading `\fB^\fR').
-Finally,
-single-digit back references are available,
-and
-\fB\e<\fR
-and
-\fB\e>\fR
-are synonyms for
-\fB[[:<:]]\fR
-and
-\fB[[:>:]]\fR
-respectively;
-no other escapes are available.

+.TH REGEX 7 "25 Oct 1995"
+.BY "Henry Spencer"
+.SH NAME
+regex \- POSIX 1003.2 regular expressions
+.SH DESCRIPTION
+Regular expressions (``RE''s),
+as defined in POSIX 1003.2, come in two forms:
+modern REs (roughly those of
+.IR egrep ;
+1003.2 calls these ``extended'' REs)
+and obsolete REs (roughly those of
+.IR ed ;
+1003.2 ``basic'' REs).
+Obsolete REs mostly exist for backward compatibility in some old programs;
+they will be discussed at the end.
+1003.2 leaves some aspects of RE syntax and semantics open;
+`\(dg' marks decisions on these aspects that
+may not be fully portable to other 1003.2 implementations.
+.PP
+A (modern) RE is one\(dg or more non-empty\(dg \fIbranches\fR,
+separated by `|'.
+It matches anything that matches one of the branches.
+.PP
+A branch is one\(dg or more \fIpieces\fR, concatenated.
+It matches a match for the first, followed by a match for the second, etc.
+.PP
+A piece is an \fIatom\fR possibly followed
+by a single\(dg `*', `+', `?', or \fIbound\fR.
+An atom followed by `*' matches a sequence of 0 or more matches of the atom.
+An atom followed by `+' matches a sequence of 1 or more matches of the atom.
+An atom followed by `?' matches a sequence of 0 or 1 matches of the atom.
+.PP
+A \fIbound\fR is `{' followed by an unsigned decimal integer,
+possibly followed by `,'
+possibly followed by another unsigned decimal integer,
+always followed by `}'.
+The integers must lie between 0 and RE_DUP_MAX (255\(dg) inclusive,
+and if there are two of them, the first may not exceed the second.
+An atom followed by a bound containing one integer \fIi\fR
+and no comma matches
+a sequence of exactly \fIi\fR matches of the atom.
+An atom followed by a bound
+containing one integer \fIi\fR and a comma matches
+a sequence of \fIi\fR or more matches of the atom.
+An atom followed by a bound
+containing two integers \fIi\fR and \fIj\fR matches
+a sequence of \fIi\fR through \fIj\fR (inclusive) matches of the atom.
+.PP
+An atom is a regular expression enclosed in `()' (matching a match for the
+regular expression),
+an empty set of `()' (matching the null string)\(dg,
+a \fIbracket expression\fR (see below), `.'
+(matching any single character), `^' (matching the null string at the
+beginning of a line), `$' (matching the null string at the
+end of a line), a `\e' followed by one of the characters
+`^.[$()|*+?{\e'
+(matching that character taken as an ordinary character),
+a `\e' followed by any other character\(dg
+(matching that character taken as an ordinary character,
+as if the `\e' had not been present\(dg),
+or a single character with no other significance (matching that character).
+A `{' followed by a character other than a digit is an ordinary
+character, not the beginning of a bound\(dg.
+It is illegal to end an RE with `\e'.
+.PP
+A \fIbracket expression\fR is a list of characters enclosed in `[]'.
+It normally matches any single character from the list (but see below).
+If the list begins with `^',
+it matches any single character
+(but see below) \fInot\fR from the rest of the list.
+If two characters in the list are separated by `\-', this is shorthand
+for the full \fIrange\fR of characters between those two (inclusive) in the
+collating sequence,
+e.g. `[0\-9]' in ASCII matches any decimal digit.
+It is illegal\(dg for two ranges to share an
+endpoint, e.g. `a\-c\-e'.
+Ranges are very collating-sequence-dependent,
+and portable programs should avoid relying on them.
+.PP
+To include a literal `]' in the list, make it the first character
+(following a possible `^').
+To include a literal `\-', make it the first or last character,
+or the second endpoint of a range.
+To use a literal `\-' as the first endpoint of a range,
+enclose it in `[.' and `.]' to make it a collating element (see below).
+With the exception of these and some combinations using `[' (see next
+paragraphs), all other special characters, including `\e', lose their
+special significance within a bracket expression.
+.PP
+Within a bracket expression, a collating element (a character,
+a multi-character sequence that collates as if it were a single character,
+or a collating-sequence name for either)
+enclosed in `[.' and `.]' stands for the
+sequence of characters of that collating element.
+The sequence is a single element of the bracket expression's list.
+A bracket expression containing a multi-character collating element 
+can thus match more than one character,
+e.g. if the collating sequence includes a `ch' collating element,
+then the RE `[[.ch.]]*c' matches the first five characters
+of `chchcc'.
+.PP
+Within a bracket expression, a collating element enclosed in `[=' and
+`=]' is an equivalence class, standing for the sequences of characters
+of all collating elements equivalent to that one, including itself.
+(If there are no other equivalent collating elements,
+the treatment is as if the enclosing delimiters were `[.' and `.]'.)
+For example, if o and \o'o^' are the members of an equivalence class,
+then `[[=o=]]', `[[=\o'o^'=]]', and `[o\o'o^']' are all synonymous.
+An equivalence class may not\(dg be an endpoint
+of a range.
+.PP
+Within a bracket expression, the name of a \fIcharacter class\fR enclosed
+in `[:' and `:]' stands for the list of all characters belonging to that
+class.
+Standard character class names are:
+.PP
+.RS
+.nf
+.ta 3c 6c 9c
+alnum	digit	punct
+alpha	graph	space
+blank	lower	upper
+cntrl	print	xdigit
+.fi
+.RE
+.PP
+These stand for the character classes defined in
+.IR ctype (3).
+A locale may provide others.
+A character class may not be used as an endpoint of a range.
+.PP
+There are two special cases\(dg of bracket expressions:
+the bracket expressions `[[:<:]]' and `[[:>:]]' match the null string at
+the beginning and end of a word respectively.
+A word is defined as a sequence of
+word characters
+which is neither preceded nor followed by
+word characters.
+A word character is an
+.I alnum
+character (as defined by
+.IR ctype (3))
+or an underscore.
+This is an extension,
+compatible with but not specified by POSIX 1003.2,
+and should be used with
+caution in software intended to be portable to other systems.
+.PP
+In the event that an RE could match more than one substring of a given
+string,
+the RE matches the one starting earliest in the string.
+If the RE could match more than one substring starting at that point,
+it matches the longest.
+Subexpressions also match the longest possible substrings, subject to
+the constraint that the whole match be as long as possible,
+with subexpressions starting earlier in the RE taking priority over
+ones starting later.
+Note that higher-level subexpressions thus take priority over
+their lower-level component subexpressions.
+.PP
+Match lengths are measured in characters, not collating elements.
+A null string is considered longer than no match at all.
+For example,
+`bb*' matches the three middle characters of `abbbc',
+`(wee|week)(knights|nights)' matches all ten characters of `weeknights',
+when `(.*).*' is matched against `abc' the parenthesized subexpression
+matches all three characters, and
+when `(a*)*' is matched against `bc' both the whole RE and the parenthesized
+subexpression match the null string.
+.PP
+If case-independent matching is specified,
+the effect is much as if all case distinctions had vanished from the
+alphabet.
+When an alphabetic that exists in multiple cases appears as an
+ordinary character outside a bracket expression, it is effectively
+transformed into a bracket expression containing both cases,
+e.g. `x' becomes `[xX]'.
+When it appears inside a bracket expression, all case counterparts
+of it are added to the bracket expression, so that (e.g.) `[x]'
+becomes `[xX]' and `[^x]' becomes `[^xX]'.
+.PP
+No particular limit is imposed on the length of REs\(dg.
+Programs intended to be portable should not employ REs longer
+than 256 bytes,
+as an implementation can refuse to accept such REs and remain
+POSIX-compliant.
+.PP
+Obsolete (``basic'') regular expressions differ in several respects.
+`|', `+', and `?' are ordinary characters and there is no equivalent
+for their functionality.
+The delimiters for bounds are `\e{' and `\e}',
+with `{' and `}' by themselves ordinary characters.
+The parentheses for nested subexpressions are `\e(' and `\e)',
+with `(' and `)' by themselves ordinary characters.
+`^' is an ordinary character except at the beginning of the
+RE or\(dg the beginning of a parenthesized subexpression,
+`$' is an ordinary character except at the end of the
+RE or\(dg the end of a parenthesized subexpression,
+and `*' is an ordinary character if it appears at the beginning of the
+RE or the beginning of a parenthesized subexpression
+(after a possible leading `^').
+Finally, there is one new type of atom, a \fIback reference\fR:
+`\e' followed by a non-zero decimal digit \fId\fR
+matches the same sequence of characters
+matched by the \fId\fRth parenthesized subexpression
+(numbering subexpressions by the positions of their opening parentheses,
+left to right),
+so that (e.g.) `\e([bc]\e)\e1' matches `bb' or `cc' but not `bc'.
+.SH SEE ALSO
+regex(3)
+.PP
+POSIX 1003.2, section 2.8 (Regular Expression Notation).
+.SH HISTORY
+Written by Henry Spencer, based on the 1003.2 spec.
+.SH BUGS
+Having two kinds of REs is a botch.
+.PP
+The current 1003.2 spec says that `)' is an ordinary character in
+the absence of an unmatched `(';
+this was an unintentional result of a wording error,
+and change is likely.
+Avoid relying on it.
+.PP
+Back references are a dreadful botch,
+posing major problems for efficient implementations.
+They are also somewhat vaguely defined
+(does
+`a\e(\e(b\e)*\e2\e)*d' match `abbbd'?).
+Avoid using them.
+.PP
+1003.2's specification of case-independent matching is vague.
+The ``one case implies all cases'' definition given above
+is current consensus among implementors as to the right interpretation.
+.PP
+The syntax for word boundaries is incredibly ugly.

- * 2. add a "long Dial(long connectionId = -1)" function which asks the user
- *    about which connection to dial (this may be done using native dialogs
- *    under NT, need generic dialogs for all others) and returns the identifier
- *    of the selected connection (it's opaque to the application) - it may be
- *    reused later to dial the same connection later (or use strings instead of
- *    longs may be?)
- * 3. add an async version of dialing functions which notify the caller about
- *    the progress (or may be even start another thread to monitor it)
- * 4. the static creation/accessor functions are not MT-safe - but is this
- *    really crucial? I think we may suppose they're always called from the

+README for wxPythonSrc-*.tar.gz
+-------------------------------
+
+Prior to version 2.3.3 of wxPython I had always made my Linux/Unix
+binaries based on the released binary of wxGTK and wxGTK-gl.  This
+imposed a few restrictions and so starting with 2.3.3 I have decided
+to do a combined binary that inlcudes wxGTK as well as wxPython.  This
+allows me a bit more flexibility and is consistent with how the
+Windows and Mac OS X binaries are built.
+
+If you are reading this file then you are probably interested in
+building your own copy of wxPython from the sources contained in this
+file.  If you wish to use the released wxGTK binary as has been done
+in the past then you can still follow the old build directions in
+wxPython/BUILD.unix.txt.  If you are building for Windows or Mac OS X
+then you should look at BUILD.win32.txt or BUILD.osx.txt respectivly.
+In all these cases you should use the IN_CVS_TREE=1 flag since this
+archive is really just a modified CVS snapshot.
+
+If, on the other hand, you would like to build Linux/Unix binaries
+with a private copy of wxGTK like what I am now distributing then
+you'll want to follow the instructions in this file.
+
+Clear as mud?  Good.  Let's get started.
+
+
+1. We'll be making a private copy of wxGTK so it doesn't conflict with
+   one used by wxGTK C++ apps that expect to have the default binary
+   installed from RPM or whatever.  I put it in /usr/lib/wxPython, but
+   you can use whatever you like.  I'll just set a variable to our wx
+   prefix to reference later:
+
+	export WXPREF=/usr/lib/wxPython
+
+
+2. Make a build directory and configure wxGTK.
+
+	cd wxPythonGTK-2.3.3   # or whatever the top-level dir is
+	mkdir build
+	cd build
+	../configure --with-gtk \
+		     --prefix=$WXPREF \
+		     --enable-rpath=$WXPREF/lib \
+		     --with-opengl \
+		     --enable-optimise \
+		     --enable-debug_flag \
+		     -with-libjpeg=builtin \
+		     --with-libpng=builtin \
+		     --with-libtiff=builtin \
+		     --with-zlib=builtin
+
+   You may want to use --enable-debug instead of --enable-optimise if
+   you need to run though a debugger and want full debugging symbols.
+
+
+3. Build and install wxGTK.  (You may need to be root for the last
+   step, depending on where your WXPREF is.)
+
+	make
+	cd ../locale
+	make allmo
+	cd ../build
+	make install
+
+4. Build and install wxPython.  If you want to use a different version
+   of Python than is found by default on the PATH then specify the
+   whole pathname in these steps.  The version of Python that runs
+   setup.py is the version wxPython will be built and installed for.
+   (You will need to be root for the install step unless your Python
+   is not in a system location.)
+
+	cd ../wxPython
+	python setup.py \
+	       IN_CVS_TREE=1 WX_CONFIG=$WXPREF/bin/wx-config \
+	       build install
+
+5. That's all!
