The following options control the processing performed by gnatcheck.
The default behavior is that all the rule checks are disabled.
A coding standard file is a text file that contains a set of rule options described above. The file may contain empty lines and Ada-style comments (comment lines and end-of-line comments). There can be several rule options on a single line (separated by a space).
A coding standard file may reference other coding standard files by including more -from=rule_option_filename options, each such option being replaced with the content of the corresponding coding standard file during processing. In case a cycle is detected (that is, rule_file_1 reads rule options from rule_file_2, and rule_file_2 reads (directly or indirectly) rule options from rule_file_1), processing fails with an error message.
