Implement the "ulimit" builtin. This is the analogon to csh's "limit" command and badly needed in sh(1) for everybody who wants to modify the system-wide limits from inside /etc/rc. The options are similar to other system's implemantations of this command, with the FreeBSD additions for -m (memoryuse) and -p (max processes) that are not available on other systems. 1995-10-19 18:42:12 +00:00			`# $Id: builtins,v 1.2 1994/09/24 02:57:23 davidg Exp $`
