Subject: [PATCH 02/11] git-p4: test debug macro
Message-ID: <1324147942-21558-3-git-send-email-pw@padd.com>
In-Reply-To: <1324147942-21558-1-git-send-email-pw@padd.com>

Call this from a test to have it pause and wait for you to
investigate.  It prints out its current directory and the
P4 environment variables.  It waits for ctrl-c before continuing
the test.

+#    "$GITP4" clone ... &&
+#    (
+#          cd "$git" &&
+#          debug &&
+#          git log --oneline >lines &&

+#
+# Go investigate when it pauses, then hit ctrl-c to continue the
+# test.  The other tests will run, and p4d will be cleaned up nicely.
+#
+# Note that the directory is deleted and created for every test run,
+# so you have to do the "cd" again.
