b[No configuration file is present.]
kdesrc-build requires a configuration file to select which KDE software modules
to build, what options to build them with, the path to install to, etc.
kdesrc-build looks for its configuration in the file `kdesrc-buildrc' in
whatever directory kdesrc-build is run from.
If no such file exists, kdesrc-build tries to use `~/.kdesrc-buildrc' (note the
leading `.')
A sample configuration suitable for KDE 4 software is included at the file
`kdesrc-buildrc-sample' which can be copied to the correct location and then
edited.
KDE Frameworks 5 users can use the `kdesrc-buildrc-kf5-sample' file which can
be copied to the correct location and then edited.
In either case b[once the configuration file is setup to your liking], you
should run:
b[kdesrc-build --metadata-only]
to download needed information about the KDE source repositories and then:
b[kdesrc-build --pretend]
to preview what kdesrc-build will do.
