Ash Documentation?

[Dallas Clement]

Can anyone please suggest a reference to some good Ash scripting
documentation?  I am trying to implement scripting like I'm using Bourne
shell and things are not behaving too well...

In particular, I'm wondering how to correctly define shell script
functions and call the functions.  I presume this is supported with the
busybox ash implementation.

Any help appreciated.
