Tool to analyze a software project and extract information about the source code

Question

I am looking for a program to analyze a software development project (i.e. a folder) and output information about the source code:

• total number of lines
• total number of files
• average files size
• number of lines/percentage of different languages
• runs on Windows

It should support a wide range of languages; at minimum (a bit flexible though):

• Javascript [crazy unlikely bonus: sub detects jQuery specifics]
• HTML/XHTML
• PHP
• Python
• CSS
• C++
• Markdown
• JSON
• XML

Bonus points for:

• Being able to analyze a local (or remote) code versioning system (GIT and/or SVN).
• (If option above supported) Ability to find number of lines/percentages by author as well as language.
• Being cross platform.
• Easy extendability to support custom languages.
• 'Pretty' graphical output as well as text output.

What you look like is typically a clone of the front page of GitHub project indicating some software statistics, no ?

If so, i would direct you to this answer on StackOverflow : How to generate stats for a GitHub project? which in turn leads to gitstats. To directly quote the former website, it provides

Here is a list of some statistics generated currently:

General statistics: total files, lines, commits, authors.

Activity: commits by hour of day, day of week, hour of week, month of year, year and month, and year.

Authors: list of authors (name, commits (%), first commit date, last commit date, age), author of month, author of year.

Files: file count by date, extensions

Lines: Lines of Code by date

It unfortunatly requires git, Python and Gnuplot, so i guess it will be more easily usable on Linux systems.
