# A simple script to swap around your Alaveteli themes when you're
# hacking on Alaveteli. By default this assumes that you have an
# 'alaveteli-themes' directory at the same level as your alaveteli git
# repository, e.g.:
#
# alaveteli
# ├── app
# ├── cache
# ...
# └── vendor
# alaveteli-themes/
# ├── alavetelitheme
# ├── asktheeu-theme
# ├── chiediamo-theme
# ├── ipvtheme
# ├── queremossabertheme
# ├── tuderechoasaber-theme
# ├── whatdotheyknow-theme
# └── yourrighttoknow
#
# However, you can override the location of your themes directory with
# the environment variable ALAVETELI_THEMES_DIR.
#
# You need to have a corresponding general.yml file called, for example:
#
# config/general-whatdotheyknow-theme.yml
# config/general-yourrighttoknow.yml
