extras

This directory is used to hold configuration programs for optional extra packages.

If a subdirectory of this directory contains an executable file setup.sh, this file is run.

The two files cctk_extradefs.h and make.extra.defn can be appended to, to add c preprocessor macros or add/modify make variables respectively. CCTK_WriteLine can be used to do this.

Note that include directories should be added to SYS_INC_DIRS and not directly to INC_DIRS.
