.SH NAME
cupsd.conf \- server configuration file for cups
.SH DESCRIPTION
The \fIcupsd.conf\fR file configures the CUPS scheduler, \fIcupsd(8)\fR.  It
is normally located in the \fI/etc/cups\fR directory. \fBNote:\fR
File, directory, and user configuration directives that used to be allowed in
the \fIcupsd.conf\fR file are now stored in the \fIcups-files.conf(5)\fR instead
in order to prevent certain types of privilege escalation attacks.
.LP
Each line in the file can be a configuration directive, a blank line,
or a comment. Comment lines start with the # character. The
configuration directives are intentionally similar to those used by the
popular Apache web server software and are described below.
