GDB, the GNU Project debugger, allows you to see what is going on `inside' another program while it executes -- or what another program was doing at the moment it crashed.

This is an installer for gdbserver, which allows you to remotely debug programs on the Pandora from your PC.
It will place gdbserver in /usr/bin and will require your password to install.
In order to connect to gdbserver, you need to have a host gdb that targets armv7l-unknown-linux-gnueabi
