PROGRAM:
NAME
psort - sort primitives in metafile as requested
SYNOPSIS
psort [ +/-x ][ +/-y ][ +/-X ][ +/-Y ] file ..
DESCRIPTION
Psort reads each metafile file in sequence and sorts primitives between globals according
to the option specification. Lower case options mean the corresponding minimum, upper
case indicates the maximum value. A '+' before the option means sort in order of
increasing values, '-' means decreasing. The order the options appear on the command line
is the order in which the extrema are examined. For example, the options -Y +x would mean
"sort on decreasing ymax, then increasing xmin values".
If no input files are specified, the standard input is read.
EXAMPLE
To sort the file "meta" in order of increasing xmax, then decreasing ymin:
psort +X -y meta
