bloat

Generate webtreemap-compatible JSON summaries of binary size.

Setup

Check out a copy of webtreemap in a webtreemap subdirectory:
```
 git clone git://github.com/martine/webtreemap.git
```
Build your binary with the -g flag to get symbols.
Run ./bloat.py --help and generate a.out.map as instructed there.
Example command line:

./bloat.py syms --map-output ~/src/llvm-svn//tools/clang/cf.map > bloat.json

Dump large symbols:

./bloat.py dump | head -20
