+# 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 ':' except on otherwise blank lines.

+libseccomp: libseccomp (Enhanced Seccomp library)
+libseccomp:
+libseccomp: The libseccomp library provides an easy to use, platform independent,
+libseccomp: interface to the Linux Kernel's syscall filtering mechanism.
+libseccomp: The libseccomp API is designed to abstract away the underlying BPF
+libseccomp: based syscall filter language and present a more conventional
+libseccomp: function-call based filtering interface that should be familiar to,
+libseccomp: and easily adopted by, application developers.
