"""Script for branching Google Test/Mock wiki pages for a new version.
SYNOPSIS
release_docs.py NEW_RELEASE_VERSION
Google Test and Google Mock's external user documentation is in
interlinked wiki files. When we release a new version of
Google Test or Google Mock, we need to branch the wiki files
such that users of a specific version of Google Test/Mock can
look up documenation relevant for that version. This script
automates that process by:
- branching the current wiki pages (which document the
behavior of the SVN trunk head) to pages for the specified
version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
NEW_RELEASE_VERSION is 2.6);
- updating the links in the branched files to point to the branched
version (e.g. a link in V2_6_FAQ.wiki that pointed to
Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
NOTE: NEW_RELEASE_VERSION must be a NEW version number for
which the wiki pages don't yet exist; otherwise you'll get SVN
errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
directory" when running the script.
EXAMPLE
$ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
$ scripts/release_docs.py 2.6 # create wiki pages for v2.6
$ svn status # verify the file list
$ svn diff # verify the file contents
$ svn commit -m "release wiki pages for v2.6"
