This macro defines the following variables: # # :: # # _WC_URL - url of the repository (at ) # _WC_ROOT - root url of the repository # _WC_REVISION - current revision # _WC_LAST_CHANGED_AUTHOR - author of last commit # _WC_LAST_CHANGED_DATE - date of last commit # _WC_LAST_CHANGED_REV - revision of last commit # _WC_INFO - output of command `svn info ' # # Subversion_WC_LOG retrieves the log message of the base revision of a # subversion working copy at a given location.
