This is free software, and you are welcome to distribute it under certain conditions. See COPYING file for more details. Note: hp-check can be run in three modes: 1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile HPLIP. 2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to successfully run. 3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies). Check types: a. EXTERNALDEP - External Dependencies b. GENERALDEP - General Dependencies (required both at compile and run time) c. COMPILEDEP - Compile time Dependencies d.
