GAH Annotated Hex Viewer

GAH Annotated Hex is an open source / free software hex viewer for GNU/Linux or other UNIX-alikes. It allows you to annotate fields and types within binary files with a C-like description language. Here's a screenshot:

The current version is 0.5 Beta

After building from source:

$ ./configure --prefix=$HOME
$ make
$ make install    # If you like

you can run the program with the name of the hex file first, and the name of the description file second (the description file is optional):

$ ./src/gah ~/pictures/dan.bmp data/bmp.gah

There are a handful of description files in the data/ subdirectory (some woefully incomplete).
