+# - Extract information from a subversion working copy
+# The module defines the following variables:
+#  Mercurial_HG_EXECUTABLE - path to hg command line client
+#  Mercurial_VERSION_HG - version of hg command line client
+#  Mercurial_FOUND - true if the command line client was found
+#  MERCURIAL_FOUND - same as Mercurial_FOUND, set for compatiblity reasons
+#
+# The minimum required version of Mercurial can be specified using the
+# standard syntax, e.g. FIND_PACKAGE(Mercurial 1.4)
+#
+# If the command line client executable is found two macros are defined:
+#  Mercurial_WC_INFO(<dir> <var-prefix>)
+#  Mercurial_WC_LOG(<dir> <var-prefix>)
+# Mercurial_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 `hg info <dir>'
+# Mercurial_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(Mercurial)
+#  IF(MERCURIAL_FOUND)
+#    Mercurial_WC_INFO(${PROJECT_SOURCE_DIR} Project)
+#    MESSAGE("Current revision is ${Project_WC_REVISION}")
+#    Mercurial_WC_LOG(${PROJECT_SOURCE_DIR} Project)
+#    MESSAGE("Last changed log is ${Project_LAST_CHANGED_LOG}")
