This thorn provides the SGRID library, which can be used to read binary neutron star initial data produced by SGRID.
Refer to the Cactus UserGuide, Sec. B2.2, in order to know how this thorn can be used in a compiled configuration and how to possibly linking another specific version, already installed steparately.
Each thorn contained in Cactus/arrangements/ExternalLibraries will automatically adopt the library version contained in the Cactus/arrangements/<library>/dist folder. In particular, the tarball in Cactus/arrangements/<library>/dist is only used if either THORN_DIR is set to BUILD or is left empty and no precompiled copy of the library is found. If another location is specified via the THORN_DIR variable in the <machine>.cfg file at compilation, then the Cactus/lib/sbin/strip-incdirs.sh script will automatically strip away (for safety reasons) the locations:
from THORN_INC_DIRS which default to THORN_DIR/include. Therefore, if there is any need for using one already installed version of one external library, the aforementioned location should be avoided (e.g. indicating /home as the THORN_DIR will work with no problems if the required library is installed there) or should be carefully checked, in order to avoid unwanted stripping. The same stripping happens to THORN_LIB_DIRS in lib/sbin/strip-libdirs.sh with a larger list of directories:

This section lists all the variables which are assigned storage by thorn ExternalLibraries/SGRID. Storage can either last for the duration of the run (Always means that if this thorn is activated storage will be assigned, Conditional means that if this thorn is activated storage will be assigned for the duration of the run if some condition is met), or can be turned on for the duration of a schedule function.
