# - Extract information from a git-svn working copy
# The module defines the following variables:
#
# If the command line client executable is found two macros are defined:
# GitSubversion_WC_INFO(<dir> <var-prefix>)
# GitSubversion_WC_INFO extracts information of a subversion working copy at
# a given location. This macro defines the following variables:
# <var-prefix>_WC_URL - url of the repository (at <dir>)
# <var-prefix>_WC_ROOT - root url of the repository
# <var-prefix>_WC_REVISION - current revision
# <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit
# <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit
# <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit
# <var-prefix>_WC_INFO - output of command `svn info <dir>'
# Example usage:
# find_package(Subversion)
# if(SUBVERSION_FOUND)
# GitSubversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
# message("Current revision is ${Project_WC_REVISION}")
# endif()
