+.TH COMPFACE 1 "25 January 1990"
+.SH NAME
+compface, uncompface \- compress and expand 48x48x1 face image files
+.SH SYNOPSIS
+.B compface
+[
+.I infile
+[
+.I outfile
+]
+] ...
+.LP
+.B uncompface
+[-X] [
+.I infile
+[
+.I outfile
+]
+] ...
+.SH DESCRIPTION
+.IX  compface  ""  "\fLcompface\fP \(em compress face image files"
+.IX  uncompface  ""  "\fLuncompface\fP \(em uncompress face image files"
+.I compface
+is a filter for generating highly compressed representations of 48x48x1
+face image files.
+.I uncompface
+is an inverse filter which performs an inverse transformation with no
+loss of data.
+The algorithm used is highly tuned for its purpose and achieves better
+than a five to one compression ratio on average.
+Arguments operate identically for both programmes.
+The first argument, if present, causes input to be taken from the named
+file instead of from standard input unless it is the string ``-''.
+A second argument, if present, causes output to go to the named file
+instead of to standard output unless it is the string ``-''.
+Subsequent pairs of arguments may be used to specify further pairs
+of input and output files.
+.LP
+The input format for
+.I compface
+(and the output format for
+.IR uncompface )
+is 48 lines each of 3 sixteen bit hexadecimal integers, comma terminated in C
+initialiser style.
+The output format of
+.I compface
+(and the input format for
+.IR uncompface )
+is some number of lines made up of a space followed by printable
+characters (in the range ``!'' to ``~'' inclusive).
+The first line contains 72 characters and following lines contain
+79 characters except that the last line may be short.
+.LP
+If the -X option is given to uncompface, it generates XBM format
+directly.
+.LP
+The amount of compression obtained varies between face image files but
+the output of
+.I compface
+averages less than 200 characters.
+The average number of output lines is three.
+.SH DIAGNOSTICS
+Exit status is normally 0.
+Possible errors include IO errors when opening, reading or writing
+files, format errors in
+.I compface
+input files and invalid arguments.
+Each results in an explanatory message on standard error and an exit status
+of 1.
+A warning will be produced if
+.I compface
+detects extra input data.
+.SH BUGS
+Nominating standard input as input more than once does not work.
