RE: [Help-jel] Identifying version of jel

[Chappelear, Jack]

 Ah, look at the dates in the jar file...
>From the manifest, it was built with an IBM JDK (1.3), so I expect that
it was build from some long lost source onsite ...
The class files in the jar file were compiled on Feb 20, 2001

The 'real' question is how painful and what benefits would I get by
upgrading to the latest version as part of a migration to Java 5.
The other option is to just go to 0.9.11 , which sound pretty stable (
going on 3 1/2 years ...)

JEL version is specified at the beginning of the README file in the
distribution. But not in the included binary jar file. :-(

The version can be guessed from the jar file size (if it is the original
one, distributed by me) or from file dates.

In your case the main contenders are:

JEL 0.9.10 (distributed since 13 Feb 2002), jar size = 33570 bytes
JEL 0.9.11 (    -"-"-"-"-"-   15 Oct 2003), jar size = 34270 bytes
JEL 2.0.0  (    -"-"-"-"-"-    1 Oct 2006), jar size = 33790 bytes

You can also distinguish between JEL 0.9 and JEL 2.0 by the absence (in
2.0) of the "gnu/jel/DVResolver.class" in the jar.

If you only have sources in CVS, then the situation is more difficult. 
First of all, because, if the sources are modified, the notion of JEL
version becomes diluted and ultimately meaningless. Also, when the
sources are imported into CVS the contents of my $id:$ tags will be
replaced and the file sizes will change... In any case, all JEL versions
are distributed through http://kinetic.ac.donetsk.ua/JEL/ (please see
the "Old Releases" section).

With the best regards,
                          Konstantin.
