# - 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>'

# find_package(Subversion)
