• Source file should be named [problem ID].[language specific extension](e.g. A.rb), in order to let AtCoderFriends find test cases or fill the submission form.
• Suffixes (start with underscore) may be added to the file name (e.g. A_v2.rb), so that you can try multiple codes for one problem.

• Compilation is not supported.
• Source generator supports Ruby, C/C++, C# and Java, and can be added by plugin or template.
