Document the release scripts really used for making releases.

End the polite fiction that build/tools/create-archive.py is used to build the
release because it isn't and all the last releases were built using different
scripts. Document their use in more details.

 Creating release files
 ----------------------
 
+The currently used release scripts need to be used from git-svn checkout and
+rely on Git to avoid problems with using non-clean trees and such. If you don't
+use Git you may use the alternative archive creation scripts in the next
+section.
+
+Follow these steps assuming the current working directory is the root of git
+working copy and you want to prepare distribution for the version x.y.z:
+
+1. Run "./build/tools/svn-find-native-eols.pl > ../eol-native" (if you have
+   an existing svn checkout, pass it to the script to make it run much faster,
+   but take care to have up to date sources in the working tree).
+
+2. Run "./build/tools/git-make-release x.y.z" to create source archives
+   ../wxWidgets-x.y.z.{7z,tar.bz2,zip} and wxWidgets_x.y.z_Headers.zip.
+
+3. Run "./build/tools/make-html-docs x.y.z" to create HTML documentation
+   archives ../wxWidgets-x.y.z.{tar.bz2,zip}
+
+4. This step must be done under Windows as it relies on having hhc.exe, the
+   Html Help compiler, in PATH: run the following commands
+
+    cd docs\doxygen
+    regen.bat chm
+    cd out
+    zip ..\..\..\wxWidgets-x.y.z-docs-chm.zip wx.chm
+
+5. This step also must be done under Windows as it uses Inno Setup to produce
+   the .exe file and it also requires the CHM file built above:
+
+    md x.y.z-sources
+    cd x.y.z-sources
+    7z x ..\wxWidgets-x.y.z.7z
+    md docs\htmlhelp
+    cp ..\docs\doxygen\out\wx.chm docs\htmlhelp
+    set WXW_VER=x.y.z
+    iscc build\tools\wxwidgets.iss

+Instructions for the previous version of release scripts

+
+NB: These scripts haven't been used since 2.8 series and may not work any longer!

 Currently our release system uses a Python 2.x script to generate releases.
 The script requires Unix utilities such as tar, zip and unix2dos and thus must
 be run either on Unix or using Cygwin on Windows. To generate a release, simply
