# This file is a dumb parser that converts values from '/l10n-release.toml' to be easily
# consumed from Python.
#
# 'l10n-release.toml' has a very simple structure, and it is reasonable to believe that this
# (very basic) algorithm will continue to work as it is changed.
#
# Alternatives to custom parsing that were considered:
# - Using standard library module --- none exists to parse TOML
# - Importing a TOML parsing module --- introduces an additional build step, complexity, and
# security risk
# - Vendoring a TOML module --- large amount of code given the use case. Introduces a security
# risk
