Make running git under other debugger-like programs easy
This allows us to run git, when using the script from bin-wrappers, under other programs. A few examples for usage within testsuite scripts: debug git checkout master debug --debugger=nemiver git $ARGS debug -d "valgrind --tool-memcheck --track-origins=yes" git $ARGS Or, if someone has bin-wrappers/ in their $PATH and is executing git outside the testsuite: GIT_DEBUGGER="gdb --args" git $ARGS GIT_DEBUGGER=nemiver git $ARGS GIT_DEBUGGER="valgrind --tool=memcheck --track-origins=yes" git $ARGS There is also a handy shortcut of GIT_DEBUGGER=1 meaning the same as GIT_DEBUGGER="gdb --args" Original-patch-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
