''' Demo of how to chain calls to multiple scripts together.
|
|
Running
|
|
python chaindemo.py infont outfont --featfile feat.csv --uidsfile uids.csv
|
|
will run execute() against psfnormalize, psfsetassocfeat and psfsetassocuids passing the font, parameters
|
|
and logger objects from one call to the next. So:
|
|
- the font is only opened once and written once
|
|
- there is a single log file produced
