+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description. Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in. You must
+# make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':'.

+set_rlimits: set_rlimits (give users access to realtime scheduling)
+set_rlimits:
+set_rlimits: It is a small program written to give unpriviledged users access to
+set_rlimits: realtime scheduling via the new rlimits added to kernel 2.6.12. The new
+set_rlimits: name reflects the fact that the program can control resource limits
+set_rlimits: rather than just those related to realtime priorities. This new version
+set_rlimits: adds a more flexible configuration file format, easier command line use
+set_rlimits: and the ability to control the memlock resource limit. Read the enclosed
+set_rlimits: README file and manpage for full details.
