It is not ’grep’ but “guix search” so it is only an internal SEO. ;-)

Well, this trivial patch is just a quick workaround at 2 levels.  One,
because Guix File Search [1] is almost done but not very popular yet.

Two, because this libarchive should be split into 2 different packages
or outputs: one for the library itself and another for the commands.

However, if a table containing what these utilities do seems
appropriated, here the description from the Debian package
’libarchive-tools’:

--8<---------------cut here---------------start------------->8---
The bsdtar program is the default system 'tar' program used on
FreeBSD. bsdtar uses the libarchive library as a backend which does all
of the work for reading and writing archives in various formats.

The bsdcpio program is the default system 'cpio' program used on
FreeBSD. bsdcpio uses the libarchive library as a backend which does all
of the work for reading and writing archives in various formats

The bsdcat program reads archived data from files or from its standard
input and uses the libarchive library to decompresses it to its standard
output. It may be used for viewing the contents of archives or for
passing it to other tools for further processing.
