This client program is separate from the core runtime, so Janet could be embedded

Set the variable module/*syspath* to the string syspath so that Janet will load system modules
from a directory different than the default. The default is set when Janet is built, and defaults to
/usr/local/lib/janet on Linux/Posix, and C:/Janet/Library on Windows.

.BR \-c\ source\ output
Precompiles Janet source code into an image, a binary dump that can be efficiently loaded later.
Source should be a path to the Janet module to compile, and output should be the file path of
resulting image. Output should usually end with the .jimage extension.

Load a Janet file before running a script or repl. Multiple files can be loaded

.B JANET_PATH
.RS
The location to look for Janet libraries. This is the only environment variable Janet needs to
find native and source code modules. If no JANET_PATH is set, Janet will look in
/usr/local/lib/Janet for modules.
To make Janet search multiple locations, modify the module.paths
array in Janet.
.RE
Stop parsing command line arguments. All arguments after this one will be considered file names
and then arguments to the script.
