Generating the glue code
========================
The command g-wrap will generate the wrappers for a given target
language. It may be invoked as follows:
For Guile:
g-wrap -target guile -api c interface-spec.gwp
For RScheme:
g-wrap -target rscheme -api c interface-spec.gwp
In both cases, g-wrap will generate a number of files containing the
glue code, documention, etc. In the guile case, presuming that the .gwp
file names the output module interface-spec and also requests an
automatically generated C header named interface-spec-autogen.h, the
following files would be generated:
`interface-spec.h'
glue code header
`interface-spec.c'
glue code
`interface-spec.html'
glue code and API documentation
`interface-spec-autogen.h'
automatically generated header for the underlying C API
