13.17.10 Binary file type(s)

The variable sys:*binary-file-type* is now documented. It provides the default file type of binary files. cl:load , sys:load-data-file and cl:require recognize this as a binary file type (in addition to sys:*binary-file-types* ).

The variable sys:*binary-file-types* is now exported and documented. It tells cl:load , sys:load-data-file and cl:require about additional file types which should be recognized as binary ("fasl") files. Add a string to the value of sys:*binary-file-types* if you want to load binary files which have an extension which is different from the value of sys:*binary-file-type* .
