+.SH NAME
+fstopgm - convert a Usenix FaceSaver(tm) file into a PGM image
+
+
+.UN synopsis
+.SH SYNOPSIS

+\fBfstopgm\fP
+[\fIfsfile\fP]
+
+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBfstopgm\fP reads a Usenix FaceSaver(tm) file as input and
+produces a PGM image as output.
+.PP
+FaceSaver(tm) files sometimes have rectangular pixels.  While
+\fBfstopgm\fP won't re-scale them into square pixels for you, it will
+give you the precise \fBpamscale\fP command that will do the job.
+Because of this, reading a FaceSaver(tm) image is a two-step process.
+First you do:
+
+.nf
+  fstopgm > /dev/null
+.fi
+
+This will tell you whether you need to use \fBpamscale.\fP
+
+Then use one of the following pipelines:
+.nf
+  fstopgm | pnmnorm
+  fstopgm | pamscale -whatever | pnmnorm
+.fi
+
+To go to PBM, you want something more like one of these:
+.nf
+  fstopgm | pamenlarge 3 | pnmnorm | pamditherbw
+  fstopgm | pamenlarge 3 | pamscale <whatever> | pnmnorm | pamditherbw
+.fi
+
+You want to enlarge when going to a bitmap because otherwise you lose
+information; but enlarging by more than 3 does not look good.
