-#!/bin/sh
-#
-# This is the script used by VZ to make wxWidgets releases. It is unofficial
-# because it must be ran from git-svn repository and not the official svn one
-# and relies on having a recent Perl installation. But it has the advantage of
-# being very simple because git knows which files should be included in the
-# distribution and we don't need to maintain the list of them ourselves but we
-# also don't run the risk of including anything unwanted.
-#
-# Another prerequisite for using it is to create the list of files to be
-# converted to DOS EOLs for Windows distribution, it must exist in the parent
-# directory and be called eol-native. This can be done using the companion
-# svn-find-native-eols.pl script. And will only need to be redone when
-# svn:eol-style property changes for any files (most likely because it will be
-# set for a newly added file).
-#
-# To summarize, here are the steps to create the release:
-#
-#   % cd $svn
-#   % $git/build/tools/svn-find-native-eols.pl > $git/../eol-native
-#   % cd $git
-#   % git svn tag WX_x_y_z
-#   % ./build/tools/git-make-release x.y.z
-#   % ... upload ../wxWidgets-x.y.z.{7z,tar.bz2,zip} ...
-#
-# If anything is wrong and some minor fixes are required, only the last two
-# steps (tagging and git-make-release) must be repeated.
