Source code include visualiser for c++
#!/usr/bin/python
import sys
import os.path
import re
# Use this like this:
# cppfind . -l autogen | grep -v test | python include_grapher.py | neato -otest3.pdf -Tpdf -Goverlap=scale -Gstart=rand
# you can replace neato with dot or any of the other graphvis commands
# What the example does is finds all files using autogen in them anywhere, and graphs who includes what (directly)

Output buffer as binary, similar to xxd in java

Simple XXD Style output from a ByteBuffer.

Refactored here without testing, so probably no-longer compiles - but should be a good starting point should I need it again.
