dump world [filename];
This dumps an executable Common Lisp image
containing all of the current NESL environment to filename.
If filename is not specified it defaults to bin/runnesl
relative to the NESL distribution tree. The NESL\
image can then be run directly rather than entering Common Lisp and
loading the NESL source files. Note that the image will typically
be very large (from 3 to 35 Megabytes) and might take a long time to
dump. Also, since it contains everything defined in the current
session, you might want to start a fresh NESL before executing
dump world.
dump vcode filename exp;
In normal operation the NESL system deletes the intermediate
VCODE files after they have been read. This command
writes a permanent copy of the VCODE program that evaluates
exp to the file filename. It is normally used for
reporting bugs (see Section 6.2). It can also be used
for creating stand-alone VCODE applications, which can be executed
by the VCODE interpreter outside of the NESL system. This is
useful for improving the startup time and memory usage of applications
once they have been debugged in the NESL system.
