[Pharo-users] Update CI books written in Pillar

Hi ! In the last version of Pillar (4.0.x), Pillar don't manage the compilation cycle. So the ./compile.sh does not work anymore. To update our CI, we use a Makefile (I advise you to use this too). You have an example on : https://github.com/pillar-markup/Pillar-Archetype/blob/master/welcome/Makefi... . In this Makefile, we create symbolic links pointing on the output directory. It causes "out of memory" on Jenkins. To solve this problem, you need to remove the symbolic links after the compilation. Personnaly, I had *find book-result -type l -exec unlink {} \;* at the end of the EnterprisePharo's Jenkins script. Cheers, Yann
