When RST-files are added or removed the corresponding locale files are added or removed automatically by the update script. However, if files need to be moved please use this Python script:
python tools_rst/rst_remap.py start
RST-files can then be freely moved and the remap script will move the locale file after:
python tools_rst/rst_remap.py finish
It is best to avoid moving/renaming files as this breaks URLs and without this script translators will lose all their work in these files. Please ask an administrator if you think something should be renamed/moved.
This script also works for image file names.
