+Shell Auto Completion
+=====================
+
+tests/test.py
+-------------
+
+### Bash
+
+Short version: copy this into your .profile file:
+
+    _cfa_test() (
+        (case $3 in
+        (--continue|--debug|--install|--timout-with-gdb)
+            echo yes no;;
+        (--arch)
+            echo x86 x64;;
+        (-I|--include|-E|--exclude)
+            $1 --list-comp | tr ' ' '\n' | sed -e 's@/[^/]\+$@/@;t;d';;
+        (*)
+            $1 --list-comp;;
+        esac) | grep -Ewoe "$2[^[:space:]]*"
+    )
+    complete -C _cfa_test tests/test.py
+
+The long version includes reading the bash manual, check for the complete
+built-in and readline programmable completion for details on how these
+commands are used. You can copy-paste the results directily into your
+terminal to test them or put them in one of the initalization files so they
+are loaded at start-up.
+
+This particular script does not handle the comma seperated options.
