# Patch .tx/config and store in the repository to enable running tx command
# Explanation:
#  - Adds 'trans.$PYDOC_LANGUAGE' to not need to pass tx pull with '-l LANGUAGE'
#  - Don't remove 'file_filter' otherwise tx pull complains
#  - Replace PO file path to a local directory (easier manual use of tx pull)
