.SH DESCRIPTION
|
| 18 |
.I Psort
|
| 19 |
reads each metafile
|
| 20 |
.I file
|
| 21 |
in sequence and sorts primitives between globals according to
|
| 22 |
the option specification.
|
| 23 |
Lower case options mean the corresponding minimum, upper case
|
| 24 |
indicates the maximum value.
|
| 25 |
A '+' before the option means sort in order of increasing
|
| 26 |
values, '-' means decreasing.
|
| 27 |
The order the options appear on the command line is the order
|
| 28 |
in which the extrema are examined.
|
| 29 |
For example, the options
|
| 30 |
.I \-Y +x
|
| 31 |
would mean "sort on decreasing ymax, then increasing xmin values".
|
| 32 |
.PP
|
| 33 |
If no input files are specified, the standard input is read.
|
| 34 |
.SH EXAMPLE
|
| 35 |
To sort the file "meta" in order of increasing xmax, then
|
| 36 |
decreasing ymin:
|
| 37 |
.IP "" .2i
|
| 38 |
psort +X \-y meta
|
