git-gui: add a simple msgfmt replacement

[thirdparty/git.git] / Makefile

all::

# Define V=1 to have a more verbose compile.
#
# Define NO_MSGFMT if you do not have msgfmt from the GNU gettext
# package and want to use our rough pure Tcl po->msg translator.
# TCL_PATH must be vaild for this to work.
