# modified.

# To install:
#  * Copy this script to "Other Sources" or wherever is appropriate in your
#    project.  Make sure it is executable.
#  * Project -> New Target... -> MaccOS X -> Other -> Shell Script Target
#  * Name the target "Versioning" or something.
#  * Open the Versioning target and click on the "Run Script" build phase
#    and select File -> Get Info
#  * Leave 'shell' as '/bin/sh' and under 'script' enter:
#
#      $SOURCE_ROOT/Other\ Sources/Versioning.sh
#
#  * Click on another build target, choose Get Info, and in General add
#    the Versioning target as one of the Direct Dependencies.
#  * Do the same for any other target where you care about the Git version.
#  * Modify the final 'touch' command in the script as needed.
#  * Now go to the Info.plist for your executable. Use "GIT_TAG" and
#    "GIT_COMMIT" for any field. I use GIT_TAG for "Bundle version" (and make
#    sure my tags are always #.#.#), and GIT_COMMIT for
#    "Bundle versions string, short." (These are preprocessor defines, not
#    shell variables, so don't use "${}" around GIT_TAG or GIT_COMMIT.)
#  * In the project’s main build settings, turn on "Preprocess Info.plist"
#    and set "Info.plist Preprocessor Prefix File" to 
#    $PROJECT_TEMP_DIR/revision.prefix.
