You can checkout sources from:
svn checkout svn://svn.berlios.de/dpml/trunk/main
The packages you should be looking at include:
* main/depot/tools/builder - this is a plugin that creates an Ant project
and parameterizes the project with a template. During build
initialization
an independent library is consulted concerning project production info
from
build listeners are added (based on the types of resources the project
declares)
* main/depot/library/common - this is the project library definition that
holds info about projects, their build, runtime and tests dependencies,
and project specific properties
* main/depot/library/console - a command line handler that launches a
a build system implementation (the default is the Ant-based builder
plugin)
Additional information is available at:
