concatenate-system

Arguments: system destination &key keyword arguments for system use only

This generic function concatenates the fasl files of the modules in system into destination. This is useful for creating one fasl from which the entire system can be loaded. Such a file can then be placed in a library or distributed.

Note that fasl files can be concatenated with Operating System tools such as the UNIX cat command. (Indeed, concatenate-system works as if it used cat, performing a byte-for-byte copying of the files with no pre/postpended or intervening headers or noise.

When concatenated fasl files are loaded, the four variables bound by load (*package*, *readtable*, *load-pathname*, and *load-truename*) are bound only once around the entire operation, not around each component file.

Concatenation of fasl files has no effect whatever on the source file information recorded for definitions in the fasl files since source-file information is entirely determined at compile-file time. (See *source-pathname*.)

Although the home package of the symbol naming this operator is the excl package, it is also exported from the defsystem package.

See also defsystem.htm for general information on the defsystem facility in Allegro CL.
