+cage was wtitten to be a creator of unbreakable padded cells for untrusted
+applications. It can be used to chroot programs that want to run as root.
+For that to work though either sysvinit or the kernel need to be patched and
+recompiled (instructions on how to go about this are included in /usr/doc).
+
+However since filesystem capabilities are implemented it can also be used
+as a 'su' command with inheritance support, similar to the 'capsh' command
+from the libcap package (but featuring chroot support). See README.SLACKWARE

+# 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 ':'.
