+.TH PICPACK 1
+.SH NAME
+.B picpack
+\- PostScript picture packing preprocessor
+.SH SYNOPSIS
+\*(mBpicpack\f1
+.OP "" options []
+.OP "" files []
+.SH DESCRIPTION
+.B picpack
+copies
+.I files
+to stdout, expanding picture inclusion requests
+(marked by the
+.MW .BP
+or
+.MW .PI
+macros) into an in-line
+format that can be passed through
+.B troff
+and handled by
+.BR dpost .
+If no
+.I files
+are specified
+or if
+.OP \-
+is one of the input
+.I files
+standard input is read.
+The following
+.I options
+are understood:
+.TP 0.75i
+.OP \-k list
+.I list
+is a comma- or space-separated string of words used to locate
+picture inclusion requests.
+The start of every line in the input
+.I files
+is compared with each word in
+.I list .
+If there is a match, the second string on the line is
+taken as the pathname of a picture file that is added
+to the output file.
+The default
+.I list
+is
+.RM `` ".BP .PI ''.
+.TP
+.OP \-q
+Suppress ``missing picture file'' error messages.
+.PP
+.B picpack
+is a trivial preprocessor that, in a sense, duplicates some of the
+picture inclusion capabilities already available in
+.BR dpost .
+.B picpack
+should not be used if your formatting command line includes
+a call to
+.BR dpost .
+Its only purpose is to combine picture files with text in a single
+file that can be passed through
+.B troff
+and unpacked, at some later time, by
+.BR dpost .
+The original picture inclusion mechanism, with files are pulled in by
+.BR dpost ,
+is the preferred approach.
+.SH EXAMPLES
+A typical application might be in a distributed printing environment
+where everything up to
+.B troff
+is run by the user and everything after
+.B troff
+is handled by a spooling daemon (perhaps
+.BR lp ).
+In that case the command line would be,
+.EX
+pic  \f2file\fP | tbl | eqn | picpack | troff -mm -Tpost | lp
+.EE
+A poor example, although one that should still work, would be,
+.EX
+pic  \f2file\fP | tbl | eqn | picpack | troff -mm -Tpost | dpost >\f2file\fP.ps
+.EE
+In this case picture inclusion requests could (and should) be handled by
+.BR dpost .
+Running
+.B picpack
+is not needed or even recommended.
+It should be dropped from any pipeline that includes a call to
+.BR dpost .
+.SH DIAGNOSTICS
+A 0 exit status is returned if
+.I files
+were successfully processed.
+.SH WARNINGS
+.PP
+Combining pictures and text using the capabilities available in
+.B dpost
+is the recommended approach and is always guaranteed to be more
+efficient than
+.BR picpack .
+Running
+.B picpack
+and
+.B dpost
+in the same pipeline makes little sense.
+.PP
+Using
+.B picpack
+will likely result in files that can no longer be reliably passed
+through other important
+.B troff
+postprocessors like
+.BR proof .
+At present
+.B picpack
+is only guaranteed to work with
+.BR dpost .
