An ini file has sections starting by the name of the section in square brackets and within each section there are key = value pairs with optional spaces around the "=" sign. The keys can only contain letters, numbers, underscore or dash. In addition there can be empty lines and lines starting with # which are comments.
Given a filename, generate a 2 dimensional hash and then print it out. Example ini file:
# comment [alpha] base = moon ship= alpha 3 [earth] # ? base=London ship= x-wing
