Gnucash uses 'g-wrap', which takes a scheme interface definition file
and generates c and scheme glue code.  As our usage of guile has
grown, so has g-wrap's sophistication about data types and memory
management semantics.  It's not perfect but it's good enough for our
purposes and getting better all the time.  

The g-wrap maintainer is Rob Browning (address@hidden); right now
the only way to get it is from the Gnucash ftp site;
ftp://ftp.gnucash.org/pub/g-wrap/source/ .  Unfortunately there have
been some major interface changes since the documentation was last
updated; the best way to figure out what's going on is to look at
examples.
