debug-here-gdb-wrapper

This program is what debug-here tells new terminals to use as a shell. It is very simple. All it does is examine the RUST_DEBUG_HERE_LIFELINE environment variable, then becomes rust-gdb via exec and hooks into the part of the source code that called the debug_here!() macro. As a user, you mostly shouldn't have to worry about what this program does. You just need to have it somewhere on your path in order to use debug_here!(). The easiest way to do that is with cargo install debug-here-gdb-wrapper.
