Ohcount - The Ohloh source code line counter

Ohcount is a library for counting lines of source code. It was originally developed at Ohloh. It supports multiple languages within a single file: for example, a complex HTML document might include regions of both CSS and JavaScript.

Ohcount has two main components: a detector which determines the primary language family used by a particular source file, and a parser which provides a line-by-line breakdown of the contents of a source file. It includes a command line tool that allows you to count individual files or whole directory trees. It also allows you to find source code files by language family, or to create a detailed annotation of an individual source file.
