There are severals ways to approach
this.<br><br>First, several of the IDE's use a project approach and
allow you to rebuild an entire project from within the
IDE.<br><br>Second, I'd consider Ant, a java  based build tool
available at http://jakarta.apache.org/ant/<br>This tool
can be run from the command  line and requires some
setup but is very flexible. If you are setting up build
environments and you need to be able to move it from the test
to production areas and don't want to have to recode
everything, this is your choice. It has a learning curve on
it but is well worth the
effort.
