jlinker-version

Arguments: &optional stream-or-key prefix t1 t2

The behavior of this function depends on the type of the stream-or-key. That argument can be a string or symbol string-equal to "<" or ">", or it can be a value suitable as the first argument to format (such as a stream, t, or nil)

Behavior when stream-or-key argument is string-equal to "<" or ">"

In this case, jlinker-version works as a boolean, testing whether the current version is earlier than or later than the version specified by the prefix, t1, and t2 arguments. prefix, t1, and t2 should all be non-negative integers. Thus, (jlinker-version :> 2) returns true for versions later than 2.0.0. (The current version in list format is the value of *jlinker-version*.)

Behavior when stream-or-key argument is suitable as the first argument to format

This function generates a nice version message from the jLinker version variables. If the stream-or-key argument is nil or omitted, the message is returned as a string; otherwise, the message is written to the stream-or-key argument. The prefix argument is text inserted at the beginning of each of the 3 lines in the message.

Example:

;;;  *jlinker-version* = 3.0.8
;;; *jlinker-comptime* = 2000-9-29 16:16:31
;;; JDK/Orb: c:\mmWork\java\jdk1.2   Direct link.
