# The following CMake macro will attempt to 'guess' which type of repository is
# associated with the current source directory. Then, base on the type of repository,
# it will extract its associated information.
#
#
# SlicerMacroExtractRepositoryInfo(VAR_PREFIX <var-prefix> [SOURCE_DIR <dir>])
#
# If no SOURCE_DIR is provided, it will default to CMAKE_CURRENT_SOURCE_DIR.
#
# The macro will define the following variables:
# <var-prefix>_WC_TYPE - Either 'git', 'svn' or 'local' - The type will also be 'svn' if 'git-svn' is used.
#
# If a GIT repository is associated with SOURCE_DIR, the macro
# will define the following variables:
# <var-prefix>_WC_URL - url of the repository (at SOURCE_DIR)
# <var-prefix>_WC_ROOT - Same value as working copy URL
# <var-prefix>_WC_REVISION_NAME - url of the repository (at SOURCE_DIR)
# <var-prefix>_WC_REVISION_HASH - current revision
# <var-prefix>_WC_REVISION - Equal to <var-prefix>_WC_REVISION_HASH if not a git-svn repository
#
# If a SVN or GIT-SVN repository is associated with SOURCE_DIR, the macro
# will define the following variables:
# <var-prefix>_WC_URL - url of the repository (at SOURCE_DIR)
# <var-prefix>_WC_ROOT - root url of the associated SVN 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
#
