rpmdev-rmdevelrpms is a script for finding and optionally removing
"development" packages, for example for cleanup purposes before starting to
build a new package.
By default, the following packages are treated as development ones and are
thus candidates for removal: any package whose name matches "-devel\\b",
"-debuginfo\\b", "-sdk\\b", or "-static\\b" (case insensitively) except gcc
requirements; any package whose name starts with "perl-(Devel|ExtUtils|Test)-";
any package whose name starts with "compat-gcc"; packages in the internal list
of known development oriented packages (see def_devpkgs in the source code);
packages determined to be development ones based on some basic heuristic
checks on the package\'s contents.
The default set of packages above is not intended to not reduce a system into
a minimal clean build root, but to keep it usable for general purposes while
getting rid of a reasonably large set of development packages. The package
set operated on can be configured to meet various scenarios.
To include additional packages in the list of ones treated as development
packages, use the "devpkgs" option in the configuration file. To exclude
packages from the list use "nondevpkgs" in it. Exclusion overrides inclusion.
The system wide configuration file is /etc/rpmdevtools/rmdevelrpms.conf,
and per user settings (which override system ones) can be specified in
~/.config/rpmdevtools/rmdevelrpms.conf or ~/.rmdevelrpmsrc (deprecated).
These files are written in Python.
