This example shows how the generation of xserver.conf is impacted by the modification of semantics for antiquotations in multiline indented strings.

Three versions are presented here:

• xserver.conf: The old version
• xserver.conf-smart: The new version, note how many blank lines are removed, and block properly indented.
• xserver.conf-smart-fixed: The version obtained with the new semantics after modifications from improve-x11.diff, in particular removing some cruft that reindents(!) blocks.

In particular, xserver.conf.diff shows the differences between xserver.conf and xserver.conf-smart-fixed.

This bash script updates a package version and source hash directly in the source files.

It uses unsafeGetAttrPos to find the files to edit, which in turn require to get access to the real attrset. This is why we have to define the overlays.
