This file controls the actual install process.
If the INSTALL file is not present in the spell, cast uses default_install:
make install
This default_install function is for the build api 2 only! In build api 1, make install is included in BUILD. Do not write spells in build api 1!!! Instead use build api 2!!!
See Build API 2 Split How-To, Build_api_2, and BUILD_split_design_doc.
