+# git-gui + gitk — Tcl/Tk GUIs for git.
+#
+# Companion to git-scm.org which builds the main git binaries with
+# `NO_TCLTK=1`. This recipe re-uses the same git source but builds
+# only the git-gui/ and gitk-git/ subdirs against Tk.
+#
+# Provides bin/git-gui (commit/history GUI) and bin/gitk (history
+# visualizer). Both invoked via `git gui` and `gitk` once on PATH.
+#
+# Closes part of pkgxdev/pantry#99 (Top 300 holdout #371).
