Comments

Single-line comments like in C++
// This is a single-line comment
Delimited comments like in C
/* This is a delimited comment */
XML single-line comments:
/// <summary> This is a single-line XML comment </summary>
XML delimited comments:
/** <summary> This is a delimited XML comment </summary> */

XML comments can only be given before declarations, not inside other fragments

Delimited comments cannot be nested
