| 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. |
