al_set_exe_name - Allegro 5 API
void al_set_exe_name(char const *path)
This override the executable name used by al_get_standard_path(3alleg5) for
ALLEGRO_EXENAME_PATH and ALLEGRO_RESOURCES_PATH.
One possibility where changing this can be useful is if you use
the Python wrapper. Allegro would then by default think that the system's
Python executable is the current executable - but you can set it to the .py
file being executed instead.
