Features and Implementation Status

PD Piglet aims to implement nearly the full set of HP Piglet commands and a few Graffy extensions as a base for version 1.0. This table is a list commands and their implementation status in PD Piglet. When available, the manual page for each command can be accessed by clicking on the command name in the first column.
