new features: - hkd now uses mmap internally for loading config files, this allows for better handling of large files and simplifies the code - using aliases no longer requires '<' in the config file, instead the alias name can be used anywhere in the following commands to be replaced - aliases are now correctly replaced - some minor fixes in the man page
