Usage: %(PROGRAM)s [-d file] [-h] [initialcolor]
Usage: %(PROGRAM)s [-d file] [-i file] [-X] [-h] [initialcolor]
Where:
--database file
-d file
Alternate location of a color database file
--initfile file
-i file
Alternate location of the initialization file. This file contains a
persistent database of the current Pynche options and color. This
means that Pynche restores its option settings and current color when
it restarts, using this file (unless the -X option is used). The
default is ~/.pynche
--ignore
-X
Ignore the initialization file when starting up. Pynche will still
write the current option settings to this file when it quits.
