[jgrapht-developers] JGraphT backport

[John V. S. <js...@gm...>]

The JGraphT development version (0.7.0alpha) in CVS requires JDK 1.5 to 
build, but I've just checked in backport support to allow it to run on 
JRE 1.4.  To use it, install Retroweaver (and JRE 1.4), then create a 
file named customBuild.properties in the same directory as build.xml and 
add these two lines:

retroweaver.dir=/path/to/full/distribution/of/retroweaver
retro.jre.dir=/path/to/jre1.4

Then run ant.  The "all" target will perform a normal build/test/jar 
sequence, and then run the backport (overwriting the class files in 
place with their retrowoven versions).  Then it will re-run all tests 
against JRE 1.4 to make sure that no dependencies on JRE 1.5 have crept 
in.  Finally, it will create an extra jar with the retrowoven classes as 
part of the distribution.

If you have comments on this process, please let me know.
