.TH 404main 1 "February 17, 2008" "ubuntu-dev-tools"
.SH NAME
404main \- check if all build dependencies of a package are in main
.SH SYNOPSIS
\fB404main\fP <\fIpackage name\fP> [<\fIdistribution\fP>]
.SH DESCRIPTION
\fB404main\fP is a script that can be used to check if a package and
all its build dependencies are in Ubuntu's main component or not.
.SH CAVEATS
\fB404main\fP will take the dependencies and build dependencies of the
packages from the distribution you have first in your
/etc/apt/sources.list file.
.PP
Also, because of this the <\fIdistribution\fP> option is NOT trustworthy; if
the dependencies changed YOU WILL GET INCORRECT RESULTS.
.SH SEE ALSO
.BR apt-cache (8)
.SH AUTHORS
\fB404main\fP was written by Pete Savage <petesavage@ubuntu.com> and
this manpage by Siegfried-Angel Gevatter Pujals <rainct@ubuntu.com>.
.PP
Both are released under the GNU General Public License, version 2 or
later.
