packages in directory i0

compiled or interpreted packages present on startup
drat Yorick interface definitions for Drat transport equation solver.
fft Yorick interface to Swarztrauber FFT routines, modified for strides.
graph Declarations of Yorick graphics functions.
hex Yorick interface definitions for hex transport equation solver.
matrix Yorick interface to LAPACK matrix solving routines.
mpy
paths When Yorick starts, it must be able to find several standard include
files which initialize the interpreter. The default paths to these
files are established when Yorick is compiled (see the Maketmpl and
Makefile files in the Yorick distribution). However, if the Yorick
binary is moved to a new site, the absolute path names of these
required i0 files may change. By editing this file and placing it
in the same directory as the Yorick executable file, you can adjust for
such path name changes, which makes it possible to port Yorick binaries.
std Declarations of standard Yorick functions.
The Codger automatic code generator program uses this file to
generate appropriate C code to initialize the various built-in
functions declared here.
This file is also used as online documentation for these functions
by Yorick's help mechanism.
