Some comments on cyclomatic complexity (McCabe's) that one wants
to check.
Added some comments
replaced 1 by EXIT_FAILURE a more portable way of exiting with error.
Added a new function that converts a gchar **array to a GSList * of gchar *
in order to reduce the number of lines of manage_command_line_options
function.
Having all static function declared on top of the file.
Printing those informations may be usefull when we will want to
debug things.
Reducing lenght and complexity of read_from_configuration_file with
convert_gchar_array_to_GSList function : complexity cut down from 13
to 11 and the number of lines from 52 to 43.
Free the array as it is not needed anymore after that
