A better command-line interface for pak. NOTE: there has been a change in

how pak gets the filename for the archive. Instead of requiring an -f
argument, it now takes the first non-option argument as the filename. If
this is a problem, it can be changed back.

Also, a manual page.

.SH NAME
pak \- The QuakeForge Packfile Tool
.SH SYNOPSIS
.B pak
<\fIcommand\fP> [\fIoption\fP]... \fIARCHIVE\fP \fIFILE\fP...
.SH DESCRIPTION
\fBpak\fP is a utility for managing pack (*.pak) archives. The format used is
compatible with Quake and Quake II. Pak archives are a convenient way to store
groups of related files. Some engines allow pak archives to be compressed
internally.
.SH COMMANDS
\fBpak\fP accepts the following arguments as a command. Only one command may be
used at a time.
.TP
.B \-c, \-\-create
Create an archive. Overwrites any contents.
.TP
.B \-t, \-\-test
Test an archive for valid formatting.
.TP
.B \-x, \-\-extract
Extract an archive. Overwrites any files in the current directory with the same
names as those inside the archive.
.TP
.B \-h, \-\-help
Show summary of options.
.TP
.B \-V, \-\-version
Show the version of pak.
.SH OPTIONS
\fBpak\fP takes the following arguments as options.
.TP
.B \-p, \-\-pad
Can be useful when creating an archive. File space is padded to a 4\-byte
boundary, assisting in the speed of loading files from the archive.
.TP
.B \-q, \-\-quiet
Inhibit some of pak's normal output.
.TP
.B \-v, \-\-verbose
Display more output than usual.
.SH "SEE ALSO"
.BR quakeforge (1)
.SH AUTHORS
\fBpak\fP was written by Bill Currie <taniwha@quakeforge.net> for QuakeForge.
Jeff Teunissen <deek@quakeforge.net> has also work on it, mostly in the
interface.
