"""

Python3 script to scrape x keyboard layout file and produce translations.
|
||
|
|
|
||
|
|
To use this script, you must have a base.lst in a standard location,
|
||
|
|
/usr/local/share/X11/xkb/rules/base.lst (this is usual on FreeBSD).
|
||
|
|
|
||
|
|
Prints out a few tables of keyboard model, layout, variant names for
|
||
|
|
use in translations.
