Keep your copyright notices
To instruct MiniME to keep a particular comment, simply place and exclamation point as the first character in the comment, for example
//! Copyright (C) 2010 Topten Software. Some Rights Reserved
It also works with C-style comments:
/*! Copyright (C) 2010 Topten Software. Some Rights Reserved */
After minification, the comments will be preserved and the exclamation point be removed.
