.SH DESCRIPTION
This program invokes filemerge to compare two versions of a file
under sccs control.  If neither option -i nor -a is specified,
the program picks
what appear to be the two most recent versions.  That is, if the
file is checked out, the current version is compared to the latest
delta.  If the file is not checked out, the latest two deltas are
compared.
.LP
If -i (interactive) is specified, some recent delta commentary is
displayed and the user is prompted for the old and new versions,
which default as described above.  Option -a (all) is similar, except
that all of the delta commentary is shown, using a pager such as "more".
.LP
Ordinarily filemerge is invoked in read-only mode.  Option -w (write)
causes filemerge to be invoked normally, so that the files can be merged.
.SH ENVIRONMENT
The environment variable PAGER is used as the executable through
which to pipe sccs prt output if option -a is specified.
If PAGER is not set, "more" is used.
