-zlib 1.1.4 is a general purpose data compression library.  All the code
-is thread safe.  The data format used by the zlib library
-is described by RFCs (Request for Comments) 1950 to 1952 in the files 
-http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate
-format) and rfc1952.txt (gzip format). These documents are also available in
-other formats from ftp://ftp.uu.net/graphics/png/documents/zlib/zdoc-index.html
-
-All functions of the compression library are documented in the file zlib.h
-(volunteer to write man pages welcome, contact jloup@gzip.org). A usage
-example of the library is given in the file example.c which also tests that
-the library is working correctly. Another example is given in the file
-minigzip.c. The compression library itself is composed of all source files
-except example.c and minigzip.c.
-
-To compile all files and run the test program, follow the instructions
-given at the top of Makefile. In short "make test; make install"
-should work for most machines. For Unix: "./configure; make test; make install"
-For MSDOS, use one of the special makefiles such as Makefile.msc.
-For VMS, use Make_vms.com or descrip.mms.
-
-Questions about zlib should be sent to <zlib@gzip.org>, or to
-Gilles Vollant <info@winimage.com> for the Windows DLL version.
-The zlib home page is http://www.zlib.org or http://www.gzip.org/zlib/
-Before reporting a problem, please check this site to verify that
-you have the latest version of zlib; otherwise get the latest version and
-check whether the problem still exists or not.
-
-PLEASE read the zlib FAQ http://www.gzip.org/zlib/zlib_faq.html
-before asking for help.
-
-Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997
-issue of  Dr. Dobb's Journal; a copy of the article is available in
-http://dogma.net/markn/articles/zlibtool/zlibtool.htm
-
-The changes made in version 1.1.4 are documented in the file ChangeLog.
-The only changes made since 1.1.3 are bug corrections:
-
-- ZFREE was repeated on same allocation on some error conditions.
-  This creates a security problem described in
-  http://www.zlib.org/advisory-2002-03-11.txt
-- Returned incorrect error (Z_MEM_ERROR) on some invalid data
-- Avoid accesses before window for invalid distances with inflate window
-  less than 32K.
-- force windowBits > 8 to avoid a bug in the encoder for a window size
-  of 256 bytes. (A complete fix will be available in 1.1.5).
-
-The beta version 1.1.5beta includes many more changes. A new official
-version 1.1.5 will be released as soon as extensive testing has been
-completed on it.

-Notes for some targets:
-
-- To build a Windows DLL version, include in a DLL project zlib.def, zlib.rc
-  and all .c files except example.c and minigzip.c; compile with -DZLIB_DLL
-  The zlib DLL support was initially done by Alessandro Iacopetti and is
-  now maintained by Gilles Vollant <info@winimage.com>. Check the zlib DLL
-  home page at http://www.winimage.com/zLibDll
-
-  From Visual Basic, you can call the DLL functions which do not take
-  a structure as argument: compress, uncompress and all gz* functions.
-  See contrib/visual-basic.txt for more information, or get
-  http://www.tcfb.com/dowseware/cmp-z-it.zip
-
-- For 64-bit Irix, deflate.c must be compiled without any optimization.
-  With -O, one libpng test fails. The test works in 32 bit mode (with
-  the -n32 compiler flag). The compiler bug has been reported to SGI.
-
-- zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1   
-  it works when compiled with cc.
-
-- on Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1
-  is necessary to get gzprintf working correctly. This is done by configure.
-
-- zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works
-  with other compilers. Use "make test" to check your compiler.
-
-- gzdopen is not supported on RISCOS, BEOS and by some Mac compilers.

-1. Compression algorithm (deflate)
-
-The deflation algorithm used by gzip (also zip and zlib) is a variation of
-LZ77 (Lempel-Ziv 1977, see reference below). It finds duplicated strings in
-the input data.  The second occurrence of a string is replaced by a
-pointer to the previous string, in the form of a pair (distance,
-length).  Distances are limited to 32K bytes, and lengths are limited
-to 258 bytes. When a string does not occur anywhere in the previous
-32K bytes, it is emitted as a sequence of literal bytes.  (In this
-description, `string' must be taken as an arbitrary sequence of bytes,
-and is not restricted to printable characters.)
-
-Literals or match lengths are compressed with one Huffman tree, and
-match distances are compressed with another tree. The trees are stored
-in a compact form at the start of each block. The blocks can have any
-size (except that the compressed data for one block must fit in
-available memory). A block is terminated when deflate() determines that
-it would be useful to start another block with fresh trees. (This is
-somewhat similar to the behavior of LZW-based _compress_.)
-
-Duplicated strings are found using a hash table. All input strings of
-length 3 are inserted in the hash table. A hash index is computed for
-the next 3 bytes. If the hash chain for this index is not empty, all
-strings in the chain are compared with the current input string, and
-the longest match is selected.
-
-The hash chains are searched starting with the most recent strings, to
-favor small distances and thus take advantage of the Huffman encoding.
-The hash chains are singly linked. There are no deletions from the
-hash chains, the algorithm simply discards matches that are too old.
-
-To avoid a worst-case situation, very long hash chains are arbitrarily
-truncated at a certain length, determined by a runtime option (level
-parameter of deflateInit). So deflate() does not always find the longest
-possible match but generally finds a match which is long enough.
-
-deflate() also defers the selection of matches with a lazy evaluation
-mechanism. After a match of length N has been found, deflate() searches for
-a longer match at the next input byte. If a longer match is found, the
-previous match is truncated to a length of one (thus producing a single
-literal byte) and the process of lazy evaluation begins again. Otherwise,
-the original match is kept, and the next match search is attempted only N
-steps later.
-
-The lazy match evaluation is also subject to a runtime parameter. If
-the current match is long enough, deflate() reduces the search for a longer
-match, thus speeding up the whole process. If compression ratio is more
-important than speed, deflate() attempts a complete second search even if
-the first match is already long enough.
-
-The lazy match evaluation is not performed for the fastest compression
-modes (level parameter 1 to 3). For these fast modes, new strings
-are inserted in the hash table only when no match was found, or
-when the match is not too long. This degrades the compression ratio
-but saves time since there are both fewer insertions and fewer searches.
-
-
-2. Decompression algorithm (inflate)
-
-2.1 Introduction
-
-The real question is, given a Huffman tree, how to decode fast.  The most
-important realization is that shorter codes are much more common than
-longer codes, so pay attention to decoding the short codes fast, and let
-the long codes take longer to decode.
-
-inflate() sets up a first level table that covers some number of bits of
-input less than the length of longest code.  It gets that many bits from the
-stream, and looks it up in the table.  The table will tell if the next
-code is that many bits or less and how many, and if it is, it will tell
-the value, else it will point to the next level table for which inflate()
-grabs more bits and tries to decode a longer code.
-
-How many bits to make the first lookup is a tradeoff between the time it
-takes to decode and the time it takes to build the table.  If building the
-table took no time (and if you had infinite memory), then there would only
-be a first level table to cover all the way to the longest code.  However,
-building the table ends up taking a lot longer for more bits since short
-codes are replicated many times in such a table.  What inflate() does is
-simply to make the number of bits in the first table a variable, and set it
-for the maximum speed.
-
-inflate() sends new trees relatively often, so it is possibly set for a
-smaller first level table than an application that has only one tree for
-all the data.  For inflate, which has 286 possible codes for the
-literal/length tree, the size of the first table is nine bits.  Also the
-distance trees have 30 possible values, and the size of the first table is
-six bits.  Note that for each of those cases, the table ended up one bit
-longer than the ``average'' code length, i.e. the code length of an
-approximately flat code which would be a little more than eight bits for
-286 symbols and a little less than five bits for 30 symbols.  It would be
-interesting to see if optimizing the first level table for other
-applications gave values within a bit or two of the flat code size.
-
-
-2.2 More details on the inflate table lookup
-
-Ok, you want to know what this cleverly obfuscated inflate tree actually  
-looks like.  You are correct that it's not a Huffman tree.  It is simply a  
-lookup table for the first, let's say, nine bits of a Huffman symbol.  The  
-symbol could be as short as one bit or as long as 15 bits.  If a particular  
-symbol is shorter than nine bits, then that symbol's translation is duplicated
-in all those entries that start with that symbol's bits.  For example, if the  
-symbol is four bits, then it's duplicated 32 times in a nine-bit table.  If a  
-symbol is nine bits long, it appears in the table once.
-
-If the symbol is longer than nine bits, then that entry in the table points  
-to another similar table for the remaining bits.  Again, there are duplicated  
-entries as needed.  The idea is that most of the time the symbol will be short
-and there will only be one table look up.  (That's whole idea behind data  
-compression in the first place.)  For the less frequent long symbols, there  
-will be two lookups.  If you had a compression method with really long  
-symbols, you could have as many levels of lookups as is efficient.  For  
-inflate, two is enough.
-
-So a table entry either points to another table (in which case nine bits in  
-the above example are gobbled), or it contains the translation for the symbol  
-and the number of bits to gobble.  Then you start again with the next  
-ungobbled bit.
-
-You may wonder: why not just have one lookup table for how ever many bits the  
-longest symbol is?  The reason is that if you do that, you end up spending  
-more time filling in duplicate symbol entries than you do actually decoding.   
-At least for deflate's output that generates new trees every several 10's of  
-kbytes.  You can imagine that filling in a 2^15 entry table for a 15-bit code  
-would take too long if you're only decoding several thousand symbols.  At the  
-other extreme, you could make a new table for every bit in the code.  In fact,
-that's essentially a Huffman tree.  But then you spend two much time  
-traversing the tree while decoding, even for short symbols.
-
-So the number of bits for the first lookup table is a trade of the time to  
-fill out the table vs. the time spent looking at the second level and above of
-the table.
-
-Here is an example, scaled down:
-
-The code being decoded, with 10 symbols, from 1 to 6 bits long:
-
-A: 0
-B: 10
-C: 1100
-D: 11010
-E: 11011
-F: 11100
-G: 11101
-H: 11110
-I: 111110
-J: 111111
-
-Let's make the first table three bits long (eight entries):
-
-000: A,1
-001: A,1
-010: A,1
-011: A,1
-100: B,2
-101: B,2
-110: -> table X (gobble 3 bits)
-111: -> table Y (gobble 3 bits)
-
-Each entry is what the bits decode to and how many bits that is, i.e. how  
-many bits to gobble.  Or the entry points to another table, with the number of
-bits to gobble implicit in the size of the table.
-
-Table X is two bits long since the longest code starting with 110 is five bits
-long:
-
-00: C,1
-01: C,1
-10: D,2
-11: E,2
-
-Table Y is three bits long since the longest code starting with 111 is six  
-bits long:
-
-000: F,2
-001: F,2
-010: G,2
-011: G,2
-100: H,2
-101: H,2
-110: I,3
-111: J,3
-
-So what we have here are three tables with a total of 20 entries that had to  
-be constructed.  That's compared to 64 entries for a single table.  Or  
-compared to 16 entries for a Huffman tree (six two entry tables and one four  
-entry table).  Assuming that the code ideally represents the probability of  
-the symbols, it takes on the average 1.25 lookups per symbol.  That's compared
-to one lookup for the single table, or 1.66 lookups per symbol for the  
-Huffman tree.
-
-There, I think that gives you a picture of what's going on.  For inflate, the  
-meaning of a particular symbol is often more than just a letter.  It can be a  
-byte (a "literal"), or it can be either a length or a distance which  
-indicates a base value and a number of bits to fetch after the code that is  
-added to the base value.  Or it might be the special end-of-block code.  The  
-data structures created in inftrees.c try to encode all that information  
-compactly in the tables.

-  Generate a table for a byte-wise 32-bit CRC calculation on the polynomial:

-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The table is simply the CRC of all possible eight bit values.  This is all
-  the information needed to generate CRC's on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.

-   Notes beyond the 1.93a appnote.txt:
-
-   1. Distance pointers never point before the beginning of the output
-      stream.
-   2. Distance pointers can point back across blocks, up to 32k away.
-   3. There is an implied maximum of 7 bits for the bit length table and
-      15 bits for the actual data.
-   4. If only one code exists, then it is encoded using one bit.  (Zero
-      would be more efficient, but perhaps a little confusing.)  If two
-      codes exist, they are coded using one bit each (0 and 1).
-   5. There is no way of sending zero distance codes--a dummy must be
-      sent if there are none.  (History: a pre 2.0 version of PKZIP would
-      store blocks with no distance codes, but this was discovered to be
-      too harsh a criterion.)  Valid only for 1.93a.  2.04c does allow
-      zero distance codes, which is sent as one code of zero bits in
-      length.
-   6. There are up to 286 literal/length codes.  Code 256 represents the
-      end-of-block.  Note however that the static length tree defines
-      288 codes just to fill out the Huffman codes.  Codes 286 and 287
-      cannot be used though, since there is no length base or extra bits
-      defined for them.  Similarily, there are up to 30 distance codes.
-      However, static trees define 32 codes (all 5 bits) to fill out the
-      Huffman codes, but the last two had better not show up in the data.
-   7. Unzip can check dynamic Huffman blocks for complete code sets.
-      The exception is that a single code would not be complete (see #4).
-   8. The five bits following the block type is really the number of
-      literal codes sent minus 257.
-   9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits
-      (1+6+6).  Therefore, to output three times the length, you output
-      three codes (1+1+1), whereas to output four times the same length,
-      you only need two codes (1+3).  Hmm.
-  10. In the tree reconstruction algorithm, Code = Code + Increment
-      only if BitLength(i) is not zero.  (Pretty obvious.)
-  11. Correction: 4 Bits: # of Bit Length codes - 4     (4 - 19)
-  12. Note: length code 284 can represent 227-258, but length code 285
-      really is 258.  The last length deserves its own, short code
-      since it gets used a lot in very redundant files.  The length
-      258 is special since 258 - 3 (the min match length) is 255.
-  13. The literal/length and distance code bit lengths are read as a
-      single stream of lengths.  It is possible (and advantageous) for
-      a repeat code (16, 17, or 18) to go across the boundary between
-      the two sets of lengths.

-   Huffman code decoding is performed using a multi-level table lookup.
-   The fastest way to decode is to simply build a lookup table whose
-   size is determined by the longest code.  However, the time it takes
-   to build this table can also be a factor if the data being decoded
-   is not very long.  The most common codes are necessarily the
-   shortest codes, so those codes dominate the decoding time, and hence
-   the speed.  The idea is you can have a shorter table that decodes the
-   shorter, more probable codes, and then point to subsidiary tables for
-   the longer codes.  The time it costs to decode the longer codes is
-   then traded against the time it takes to make longer tables.
-
-   This results of this trade are in the variables lbits and dbits
-   below.  lbits is the number of bits the first level table for literal/
-   length codes can decode in one step, and dbits is the same thing for
-   the distance codes.  Subsequent tables are also less than or equal to
-   those sizes.  These values may be adjusted either when all of the
-   codes are shorter than that, in which case the longest code length in
-   bits is used, or when the shortest code is *longer* than the requested
-   table size, in which case the length of the shortest code in bits is
-   used.
-
-   There are two different values for the two tables, since they code a
-   different number of possibilities each.  The literal/length table
-   codes 286 possible values, or in a flat code, a little over eight
-   bits.  The distance table codes 30 possible values, or a little less
-   than five bits, flat.  The optimum values for speed end up being
-   about one bit more than those, so lbits is 8+1 and dbits is 5+1.
-   The optimum values may differ though from machine to machine, and
-   possibly even between compilers.  Your mileage may vary.

-.TH ZLIB 3 "11 March 2002"
-.SH NAME
-zlib \- compression/decompression library
-.SH SYNOPSIS
-[see
-.I zlib.h
-for full description]
-.SH DESCRIPTION
-The
-.I zlib
-library is a general purpose data compression library.
-The code is thread safe.
-It provides in-memory compression and decompression functions,
-including integrity checks of the uncompressed data.
-This version of the library supports only one compression method (deflation)
-but other algorithms will be added later and will have the same stream interface.
-.LP
-Compression can be done in a single step if the buffers are large enough
-(for example if an input file is mmap'ed),
-or can be done by repeated calls of the compression function.
-In the latter case,
-the application must provide more input and/or consume the output
-(providing more output space) before each call.
-.LP
-The library also supports reading and writing files in
-.I gzip
-(.gz) format
-with an interface similar to that of stdio.
-.LP
-The library does not install any signal handler. The decoder checks
-the consistency of the compressed data, so the library should never
-crash even in case of corrupted input.
-.LP
-All functions of the compression library are documented in the file
-.IR zlib.h.
-The distribution source includes examples of use of the library
-the files
-.I example.c
-and
-.IR minigzip.c .
-.LP
-A Java implementation of
-.IR zlib
-is available in the Java Development Kit 1.1
-.IP
-http://www.javasoft.com/products/JDK/1.1/docs/api/Package-java.util.zip.html
-.LP
-A Perl interface to
-.IR zlib ,
-written by Paul Marquess (pmarquess@bfsec.bt.co.uk)
-is available at CPAN (Comprehensive Perl Archive Network) sites,
-such as:
-.IP
-ftp://ftp.cis.ufl.edu/pub/perl/CPAN/modules/by-module/Compress/Compress-Zlib*
-.LP
-A Python interface to
-.IR zlib
-written by A.M. Kuchling <amk@magnet.com>
-is available from the Python Software Association sites, such as:
-.IP
-ftp://ftp.python.org/pub/python/contrib/Encoding/zlib*.tar.gz
-.SH "SEE ALSO"
-Questions about zlib should be sent to:

-or, if this fails, to the author addresses given below.
-The zlib home page is:
-.IP
-http://www.cdrom.com/pub/infozip/zlib/
-.LP
-The data format used by the zlib library is described by RFC
-(Request for Comments) 1950 to 1952 in the files: 
-.IP
-ftp://ds.internic.net/rfc/rfc1950.txt (zlib format)

-See the distribution directory with respect to requirements
-governing redistribution.
-The deflate format used by
-.I zlib
-was defined by Phil Katz.
-The deflate and
-.I zlib
-specifications were written by L. Peter Deutsch.
-Thanks to all the people who reported problems and suggested various
-improvements in
-.IR zlib ;
-who are too numerous to cite here.

-     The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed
-  data.  This version of the library supports only one compression method
-  (deflation) but other algorithms will be added later and will have the same
-  stream interface.
-
-     Compression can be done in a single step if the buffers are large
-  enough (for example if an input file is mmap'ed), or can be done by
-  repeated calls of the compression function.  In the latter case, the
-  application must provide more input and/or consume the output
-  (providing more output space) before each call.
-
-     The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio.
-
-     The library does not install any signal handler. The decoder checks
-  the consistency of the compressed data, so the library should never
-  crash even in case of corrupted input.

-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full. It may introduce some
-  output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows. deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly. If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly. This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).
-    Some output may be provided even if flush is not set.
-
-  Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming
-  more output, and updating avail_in or avail_out accordingly; avail_out
-  should never be zero before the call. The application can consume the
-  compressed output when it wants, for example when the output buffer is full
-  (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK
-  and with zero avail_out, it must be called again after making room in the
-  output buffer because there might be more output pending.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far. (In particular
-  avail_in is zero after the call if enough output space has been provided
-  before the call.)  Flushing may degrade compression for some compression
-  algorithms and so it should be used only when necessary.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired. Using Z_FULL_FLUSH too often can seriously degrade
-  the compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out).
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there
-  was enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error. After
-  deflate has returned Z_STREAM_END, the only possible operations on the
-  stream are deflateReset or deflateEnd.
-  
-    Z_FINISH can be used immediately after deflateInit if all the compression
-  is to be done in a single step. In this case, avail_out must be at least
-  0.1% larger than avail_in plus 12 bytes.  If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() sets strm->adler to the adler32 checksum of all input read
-  so far (that is, total_in bytes).
-
-    deflate() may update data_type if it can make a good guess about
-  the input data type (Z_ASCII or Z_BINARY). In doubt, the data is considered
-  binary. This field is only for information purposes and does not affect
-  the compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example

-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this

-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state. memLevel=1 uses minimum memory but
-   is slow and reduces compression ratio; memLevel=9 uses maximum memory
-   for optimal speed. The default value is 8. See zconf.h for total memory
-   usage as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm. Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), or Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match).  Filtered data consists mostly of small values with a
-   somewhat random distribution. In this case, the compression algorithm is
-   tuned to compress them better. The effect of Z_FILTERED is to force more
-   Huffman coding and less string matching; it is somewhat intermediate
-   between Z_DEFAULT and Z_HUFFMAN_ONLY. The strategy parameter only affects
-   the compression ratio but not the correctness of the compressed output even
-   if it is not set appropriately.

+README for wxLayout classes
+---------------------------
+
+All the source in this directory is copyrighted under the
+LGPL (GNU LIBRARY PUBLIC LICENSE), by Karsten Ballueder <ballueder@usa.net>.
+
+
+This is still work in progress, so if you want to make any significant
+changes, please get in touch with me before.
+
+There are three building blocks for rich text editing:
+
+wxllist :
+
+The wxLayoutList layout engine. It is a linked list of wxLayoutObjects
+which can arrange and display them on any wxDC. I am trying to keep
+this class as simple as possible, to be just the core layout
+engine. All "convenience" functions should be defined in classes built 
+on top of this.
+The wxLayoutList is derived from kbList, a double-linked list with an
+interface modelled after the STL list. As wxLayoutList depends on the
+way kbList treats iterators (i.e. the iterator value after an insert() 
+or erase() operation), I don't feel like rewriting it for wxList.
+
+wxlwindow :
+
+Contains a class wxLayoutWindow, derived from wxScrolledWindow which
+can directly be used as a rich-text display or editing window. The
+function responsible for keyboard handling is virtual and can be
+overloaded for different keybindings. wxLayoutWindow can sent fake
+menu-events to the application to react to the user clicking on
+objects.
+
+wxlparser:
+
+Contains several high level functions operating on
+wxLayoutList. Currently implemented is inserting of text (including
+linebreaks) and export of objects, text or html.
+Planned for the future is an html parser for importing html.
+
+
+wxLayout.cpp is a simple test program. It will export Text and HTML to
+stdout and demonstrate some of the features and bugs of wxLayoutList.
+
+There are still things to do and I'm working on them. :-)
