#.rst:
# FindSubversion
# --------------
#
# Extract information from a subversion working copy
#
# The module defines the following variables:
#
# ::
#
#   Subversion_SVN_EXECUTABLE - path to svn command line client
#   Subversion_VERSION_SVN - version of svn command line client
#   Subversion_FOUND - true if the command line client was found
#   SUBVERSION_FOUND - same as Subversion_FOUND, set for compatibility reasons
#
#
#
# The minimum required version of Subversion can be specified using the
# standard syntax, e.g.  find_package(Subversion 1.4)
#
# If the command line client executable is found two macros are defined:
#
# ::
#
#   Subversion_WC_INFO(<dir> <var-prefix>)
#   Subversion_WC_LOG(<dir> <var-prefix>)
#
# Subversion_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>'
#
# Subversion_WC_LOG retrieves the log message of the base revision of a
# subversion working copy at a given location.  This macro defines the
# variable:
#
# ::
#
#   <var-prefix>_LAST_CHANGED_LOG - last log of base revision
#
# Example usage:
#
# ::
#
#   find_package(Subversion)
#   if(SUBVERSION_FOUND)
#     Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project)
#     message("Current revision is ${Project_WC_REVISION}")
#     Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project)
#     message("Last changed log is ${Project_LAST_CHANGED_LOG}")
#   endif()
