After installing Python:

== Install Web2Py ==
As a Developer, it is best to run the Trunk version of Web2Py, so that you can fine-tune the version that you have installed & get involved with the Web2Py developer community.
''Note: If you have a slow internet connection, and {{{bzr branch}}} does not complete, see below.''
{{{
bzr branch lp:~mdipierro/web2py/devel web2py
}}}

There are occasional issues with the latest Trunk, so you may need to try a slightly older revision.
{{{
cd web2py
bzr revno
bzr revert -r <earlier revision>
}}}
If you have a slow internet connection, the {{{bzr branch}}} of Web2Py may not complete, due to a Launchpad timeout (this is a reported problem). In this case, you can do a "lightweight checkout", which does not provide a full revision history, and cannot be used to submit code for Web2Py.
{{{
bzr checkout --lightweight lp:~mdipierro/web2py/devel web2py
}}}

== Install Eden ==
As a Developer, you should generally run the Trunk version of Eden, so that you can submit patches against the latest code:
{{{
cd web2py/applications
bzr branch lp:sahana-eden eden
}}}

NB Note the fact that we ensure that the name of the web2py application has no hyphen in, as otherwise it cannot run under Apache!

== Install Eclipse ==
If you want a graphical debugger to set breakpoints & step through code then it is recommended to install Eclipse:
