+#autoload
+
+# This function completes POSIX capabilities for Linux.
+# Many command line utilities expect different syntax to encode various kinds
+# of capability names or sets, so this function tries to be as generic as
+# possible. It accepts compadd options to allow variations on the exact
+# generated completion matches.
+#
+# Usage examples:
+#
+# Complete full capability names:
+#   _capabilities -p cap_
+# Sort the completion list by capability number:
+#   _capabilities -o nosort
+
+# The list of Linux capabilities is taken from include/uapi/linux/capability.h
+# and subject to the following pipe filter:
+# grep 'define CAP' | sed -r 's/^[[:space:]]*#define[[:space:]]+CAP_//; s/[[:space:]]+[0-9]+$//' | tr '[[:upper:]]' '[[:lower:]]'
