=head1 NAME

kde-build - Updates and recompiles a tree of KDE modules

=head1 SYNOPSIS

        kde-build

=head1 DESCRIPTION

kde-build has been designed to keep a local copy of several KDE
modules up to date and recompile them. Those modules have to be saved in a
common directory, e.g. something like

    ~/kde-src/
      |
      +-> tdelibs/
      |
      +-> tdebase/
      |
      \-> tdenetwork/

In this case, the KDE source directory would be ~/kde-src/. The script will
take care of compiling them in the correct order, checks for dependencies
and resolves them as far as possible.

Please note that, prior to first invocation of the script, the configuration
file 'F<kde-buildrc>' has to be modified to reflect the local environment,
such as paths etc.

=head1 RETURN VALUE

The following error codes are returned by the script.

0 - No error seems to have occured.

1 - The script could not change into the directory of a module.

2 - The script could not open the file 'Makefile.in' of a module.

3 - The configuration of a module failed.

4 - The compilation of a module failed.

5 - The installation of a module failed.

6 - An invalid source directory was specified.

7 - An invalid Qt directory was specified.

11 - The configuration file F<kde-buildrc> couldn't be loaded.

12 - Both CVS_CLEAN and INCREMENTAL_BUILD were set

13 - Both BUILD_CLEAN and INCREMENTAL_BUILD were set

=head1 EXAMPLES

        cd ~/scripts/; vi ./kde-buildrc; ./kde-build

On Debian systems, an example F<kde-buildrc> can be found in
the directory /usr/share/doc/tdesdk-scripts/.

=head1 BUGS

Probably.

=head1 TODO

Add a DIAGNOSIS section to this man page.
