Yes. It lists functions but fairly little else.. :\

In particular, gcry_sexp_nth_mpi() doesn't describe the int mpifmt
parameter. It seems from the libgcrypt source code that this is
actually an enum gcry_mpi_format, but the manual also doesn't say how
to learn what to pass for that parameter. The sexp in question comes
from gcry_pk_sign() but that also says nothing about how MPIs are
stored in the result.. I looked at dsa.c in libgcrypt source and
guessed..
