Help

❯ ./ini-parser help
Exactly two positional arguments are required:
1. source file
2. query/flag "lint"

Single query either:
1) fetches multiple variables separated by whitespace
2) performs operations from "+-*/" set

IMPORTANT: all operations are conducted sequentially
(in contradiction to the laws of mathematics)

Maximal supported line length is 1024 characters
Maximal output size is 1024 characters
