{-
Runs hledger doctests.
Usage examples: in hledger source dir,
make ghci-doctest, :main [--verbose] [--slow] [CIFILEPATHSUBSTRINGS]
or:
stack test hledger-lib:test:doctests [--test-arguments '[--verbose] [--slow] [CIFILEPATHSUBSTRINGS]']
Arguments are case-insensitive file path substrings.
--verbose shows files being searched for doctests and progress while running.
--slow reloads ghci between each test (https://github.com/sol/doctest#a-note-on-performance).
