Version 176 is out.

Hi all,

TXR 176 is out; binaries at Bintray.

In this release, most of the changes relate to the new FFI.  The functionality is much more complete and better debugged.

I added dir-name and base-name functions for working with paths, and exposed the POSIX realpath function with a wrapper.

The Awk macro has a new feature: the (again) operator repeats all the rules for the current record, similarly to how (next) goes to the next record. This feature has no counterpart in POSIX Awk, nor GNU Awk.
