# A set of functions to read options files
module OptionsFileParser
# Eval the contents of options_file_path, return as an OptionsHash
#
# Options file is assumed to contain extra options stored in a Hash
#
# ie,
# {
# :debug => true,
# :tests => "test.rb",
# }
#
# @param [String] options_file_path The path to the options file
#
# @example
# options_hash = OptionsFileParser.parse_options_file('sample.cfg')
# options_hash == {:debug=>true, :tests=>"test.rb", :pre_suite=>["pre-suite.rb"], :post_suite=>"post_suite1.rb,post_suite2.rb"}
#
# @return [OptionsHash] The contents of the options file as an OptionsHash
# @raise [ArgumentError] Raises if options_file_path is not a path to a file
# @note Since the options_file is Eval'ed, any other Ruby commands will also be executed, this can be used
# to set additional environment variables

# scope. It is important that the variable 'options_file_path' is
# accessible, because some existing options files (e.g. puppetdb) rely on
# that variable to determine their own location (for use in 'require's, etc.)
