Mod.sources:  Volume 3, Issue 30
Submitted by: Robert Viduya <gatech!gitpyr!robert>


The following is a program that I posted late last january.  Due to requests
on net.info-terms, I'm reposting it.

The program converts termcap database files to terminfo source files.  It
reads the termcap file from standard input and writes the terminfo source
to standard output.  I tried to be as complete as possible, but I wasn't
able to implement some things due to ambiguous documentation.  The
unimplemented parts are in the %-escapes.  I wasn't sure about some of
the more exotic termcap %-escapes like '%B'.  However, things like '%c',
'%d', '%2d' and '%+' are implemented.

		as usual, send bug reports...
