# REcon 2006 - GDB <-> IDA link demo
#
# Allows for the ability to link up GDB on any platform/architecture with IDA.
#
# Load the gdbinit file, and it adds commands like:
#   idasi     - Step instruction (si) and have IDA follow along
#   idafollow - Move IDA to the current GDB $pc
#   idabreak  - Breakpoint on the current IDA ea
#   idacmt    - Add an IDA comment and the current GDB $pc
#
# Note: Might need to switch the unpack('V') for non-intel architectures.
#       Should probably use 'L' since it will run on the same machine as GDB.
#
