minor edit

 Comment your source code extensively using C comments (/* comment */), DO NOT

 use C++ comments (// this style). Commented code is quality code and enables

 future modifications much more. Uncommented code much more risk being

 completely replaced when someone wants to extend things, since other persons'

 source code can get quite hard to read.

General Style

 improve it, all new features and functions that are added need to be tested

 in the test suite. Every feature that is added should get at least one valid

 test case that verifies that it works as documented. If every submitter also

 post a few test cases, it won't end up as a heavy burden on a single person!
