An embedded comment is text in a MEL file that is ignored when the file is read in.
If a line in the file contains two consecutive slashes ("//"), everything from there to the end of the line is considered to be a comment. This is commonly known as a "C++ style comment".
If a line in the file contains a slash followed by an asterisk ("/*"), everything from there on is considered a to be comment, until the next occurrence of an asterisk followed by a slash ("*/"). This is commonly known as a "C style comment".
