The findutils package contains programs which will help you locate
files on your system.  The find utility searches through a hierarchy
of directories looking for files which match a certain set of criteria
(such as a filename pattern).  The xargs utility builds and executes
command lines from standard input arguments (usually lists of file
names generated by the find command).

Note that this port will install these utilities with a 'g' prefix,
e.g. gfind, but the texinfo documentation will refer to them without
the 'g' prefix.
