Set of preproc macros to be used by rpkg utility. They are designed to dynamically generate certain parts of rpm spec files. You can use those macros also without rpkg by: $ cat <file_with_the_macros> | preproc -s /usr/lib/rpkg.macros.d/all.bash -e INPUT_PATH=<file_with_the_macros> INPUT_PATH env variable is passed to preproc to inform macros about the input file location. The variable is used to derive INPUT_DIR_PATH variable which rpkg macros use. If neither INPUT_PATH nor INPUT_DIR_PATH are specified, INPUT_PATH will stay empty and INPUT_DIR_PATH will default to '.' (the current working directory). Another option to experiment with the macros is to source /usr/lib/rpkg.macros.d/all.bash into your bash environment Then you can directly invoke the macros on your command-line as bash functions. See content in /usr/lib/rpkg.macros.d to discover available macros. Please, see man rpkg-macros for more information.
