<Line-eaters? We aint got no stinkin' line-eaters!>
Here is the program I wrote to make printouts from DirMaster data
files. Since I haven't seen anything in binaries or sources for a long time
I'm just going to post the whole source file (~190 lines). The program is
made for Unix. Porting it to Amy is left as an exercise for the reader (don't
you HATE it when they say that??)
The program accepts many options for various output formats. They
are all documented in the source code. Type 'dirprint' with no options or
filenames to get a quick explanation of the options.
Cut off everything above the cut line, and don't forget to remove
my .signature from the bottom.
Enjoy,
Pete

Dirprint 1.0
System: Unix
Directory printer. Takes DirMaster data files and outputs them in
a more readable format.
Usage: dirprint [options] <DirMaster-File>
options: -v <Volume name> print only entries on this volume
for multi-word volume names, enclose in quotes
-d <n> print only to this depth
( -d 0 prints only volume names )
-p print page breaks (^L) between volumes
-t "Title line" print this header at top
future options: <Volume name> can be a regular expression (wild cards)
or a list of names/expressions.
-f <filter-file> filters output against list of unwanted
files in <filter-file>. Each line has
one filename expression.
eg: *.info
*-Handler
c/failat
c/if
fonts/*
It is case-insensitive, allows regular
expressions, and can match full path-
names.
