# The following code is run just once. But it is encapsulated in a function
# to benefit of 'local' variables.
#
# What we do here:
# 1. Setup variables that can be used by the user: the "API" of liquidprompt
# for config/theme. Those variables are local to the function.
# In practice, this is only color variables.
# 2. Setup default values
# 3. Load the configuration
