 13.1.1 Init Snarfing with guile-snarf
 -------------------------------------
 
 When writing C code for use with Guile, you typically define a set of C
 functions, and then make some of them visible to the Scheme world by
 calling the `scm_c_define_gsubr' function; a C function published in
 this way is called a "subr".  If you have many subrs to publish, it can
 sometimes be annoying to keep the list of calls to `scm_c_define_gsubr'
 in sync with the list of function definitions.  Frequently, a
 programmer will define a new subr in C, recompile the application, and
 then discover that the Scheme interpreter cannot see the subr, because
 of a missed call to `scm_c_define_gsubr'.
 
    Guile provides the `guile-snarf' command to manage this problem.
 Using this tool, you can keep all the information needed to define the
 subr alongside the function definition itself; `guile-snarf' will
 extract this information from your source code, and automatically
 generate a file of calls to `scm_c_define_gsubr' which you can
 `#include' into an initialization function.
