  31 """Script for branching Google Test/Mock wiki pages for a new version.
  32
  33 SYNOPSIS
  34        release_docs.py NEW_RELEASE_VERSION
  35
  36        Google Test and Google Mock's external user documentation is in
  37        interlinked wiki files.  When we release a new version of
  38        Google Test or Google Mock, we need to branch the wiki files
  39        such that users of a specific version of Google Test/Mock can
  40        look up documenation relevant for that version.  This script
  41        automates that process by:
  42
  43          - branching the current wiki pages (which document the
  44            behavior of the SVN trunk head) to pages for the specified
  45            version (e.g. branching FAQ.wiki to V2_6_FAQ.wiki when
  46            NEW_RELEASE_VERSION is 2.6);
  47          - updating the links in the branched files to point to the branched
  48            version (e.g. a link in V2_6_FAQ.wiki that pointed to
  49            Primer.wiki#Anchor will now point to V2_6_Primer.wiki#Anchor).
  50
  51        NOTE: NEW_RELEASE_VERSION must be a NEW version number for
  52        which the wiki pages don't yet exist; otherwise you'll get SVN
  53        errors like "svn: Path 'V1_7_PumpManual.wiki' is not a
  54        directory" when running the script.

  57        $ cd PATH/TO/GTEST_SVN_WORKSPACE/trunk
  58        $ scripts/release_docs.py 2.6  # create wiki pages for v2.6
  59        $ svn status                   # verify the file list
  60        $ svn diff                     # verify the file contents
  61        $ svn commit -m "release wiki pages for v2.6"
