.Nm what
.Nd "show what versions of object modules were used to construct a file"
.Sh SYNOPSIS
.Nm what
.Ar name Ar ...
.Sh DESCRIPTION

reads each file
.Ar name
and searches for sequences of the form
.Dq \&@(#)
as inserted by the source code control system.  It prints the remainder
of the string following this marker, up to a null character, newline, double
quote, or
.Dq \&> character.
.Sh BUGS
As
.Bx
is not licensed to distribute
.Tn SCCS
this is a rewrite of the
.Nm what
command which is part of
.Tn SCCS ,
and may not behave exactly the same as that
command does.
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.0 .
