+This is a minimal fork of Arch's `devtools'.
+
+It is a fork in that bugs are fixed and features added.
+  This happens on the "complete" branch.  Most development should happen here,
+  and it should be able to be merged back into devtools.
+It is minimal in that it doesn't include most of what is in devtools.
+  This happens on the "master" branch.
+
+A sample .git/config file is included to make it easy to merge from devtools.
+
+Tags in the format "%YYYY%MM%DD" are devtools.
+Tags in the format "v%YYYY%MM%DD" are chroottools.
