-# "Magic" CSVs simply exist to make life easier: they permit comments, blank
-# lines, variables, sub-delimiter expansion, and any number of ranges per line.
-# Ranges will be expanded in every combination, making rate tables highly
-# maintainable.
-#
-# Variables are also supported when defined using :var=val. Variables may
-# expand into ranges, 'cause they're awesome. Multiple variables may be
-# delimited by semi-colons, as may multiple values.
-#
-# For example:
-# :foo=1--3
-# $foo;7;9--10:$foo, 5--10
-#
-# Would generate:
-# 1, 5
-# 1, 6
-# ...
-# 5, 10
-# 2, 5
-# ...
-# 9, 5
-# ...
-# 1, 5
-# 1, 6
-# ...
