Contributing to GDB

GDB is a collaborative project that relies on contributions.  You can
help with this!  You may wish to fix bugs, improve testing, port GDB to
a new platform, update documentation, add new features or optimizations,
contribute to the mailing lists or official GDB website, etc.  We welcome
all of the above and feel free to ask on the GDB mailing lists if you are
looking for feedback or for people to review a work in progress.
