| [PATCH] merge gphelp and paridoc_to_pod |
I merged my 2pod converter with gphelp (trying to affect gphelp as
little as possible, since I do not know a simple way to test it). The
results of conversion to POD are not stellar, but quite useful (at
least when this POD is converted to IBM online book format, other
converters may be not up to task).
Enjoy,
Ilya
P.S. Online books are viewable on AIX, IBM PC-DOS, and OS/2 (native)
and Win* (with xview.exe present).
