ttx-l-example.py

# Usage:
#     mono ipy.exe ttx-l-example.py <fontfile1> <fontfile2> ...

# This script does the same thing as "ttx -l", except
# it will recurse through member fonts in a ttc and also take
# multiple font file arguments.

# Tips:
#     "mono ipy.exe -h" to get options.
#         -X:ColorfulConsole - useful on terminal with a light background
#                              (somehow forground color is hard-coded to white)
