[DFTB-Plus-User] How to use as a library

[Ben Hourahine]

Hello Michael,

the 19.1 release (in the next few weeks) will have examples of calling
the API.

You can check the pre-release candidate out at the moment on the master
branch at

https://github.com/dftbplus/dftbplus

with some examples in C and Fortran that use the library in the
test/api/mm/testers directory and some information in the manual.

This covers examples where forces are returned to an external driving code.

You can also use an iPi style socked interface to the code (see examples
in the

test/prog/dftb+/sockets/

directory.

Regards

Ben
