less: run lessc with --relative-urls so relative paths are rewritten 25e079891ff5 broke select2 - it did for example no longer display the search symbol in the input field. The css had a relative path to 'select2.png' which no longer was correct when the literal reference moved to style.css . Bootstrap had the same issue with '../fonts/glyphicons-halflings-regular.*' ... but we do not rely much on that. As a quick fix, just adjust the relative reference and keep pointing at the original location. A next step might be to copy files around in a cross platform compliant way, reliably at the right point in the development/build/install process.

# requirements.txt file for use as "pip install -r requirements.txt" as a
# readthedocs compatible alternative to "pip install -e ." which is a working
# alternative to "setup.py develop" which doesn't work with Mercurial 3.7
