Last time I ranted about refactoring. This already happened and the refactored version together with an additional tool is online now. In this context the project was taken out of the incubator repository (the remainders there are considered legay) and migrated to diy-gnupg (do It Yourself - GnuPG).
Now there is a file self-compile/etc/local.conf created when it does not exist. It is copied from a template and will not be changed by updates to the git repository. You can customize your preferred settings there.
The script self-compile/bin/unpack-source.sh will decompress the bzip2 files and extract the source code from the tarballs. It does not matter where you store the folder self-compile in your file system tree, since the scripts are portable and will figure out their location and the location of the configuration and shared library for error handling at runtime, but it is important to keep all the folders bin, etc and lib next to each other.
Unfortunately the refactoring and migration took longer as expected, thus I won't present this part today. The work which is done now was very important for the structure of the project. But please, feel free to play around for yourself. The working environment can easily be reproduced at any time - that is what those scripts are for.
To be continued...
