set_unicharset_properties issue

[visa...@gmail.com]

I am training data for 3.0.3.

One step in the Github Wiki  is:

training/set_unicharset_properties -U input_unicharset -O output_unicharset --script_dir=training/langdata

but there is no such script the directory.

This wiki is about 3.03–3.05.  I need the correct dir of the script.

Thanks!
