# This file is used to automatically extract the SVN revision number and
# create a C include file.

# In MSVS, you can add the following Pre-Build Step to use this script:
#   cd $(InputDir)core\build
#   c:\Python24\python.exe make-svn-rev-header.py

# This is intended for use with a custom version.cpp,
# as described in version.cpp
