Package

Change-package

Modifying constructor for package structures.

Syntax

(change-package x 
                [:file <file>])

This is an often useful alternative to make-package.

We construct a new package structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

Macro: change-package

                         'change-package
                         'nil))
