The main documentation is availiable via --help and near the top of any bash
script files which sit next to this file.
-Files ending in -function are for sourcing then calling as a function. Files
-without -function are exactly the same except they are for calling as a script.
+The script file can be stripped of the last line and used as a function
+instead of a script.
