#2 Additional Map files

[Nik Trevallyn-Jones]

I've just discovered that multiple Map files can be
specified in the .hs file.

This would make it very easy to include Map files
containing definitions for CSH (Context-Sensitive-Help).

I propose adding to the HS file page so that additional
Map file(s) can be specified.

I am happy to code support for this.

Cheers!
Nik
