 Hi guys!

 We are currently using py27-fabric for a couple of scripts to deploy code
 for various (more then 50) projects to a remote server over ssh.
 Our scripts are currently only compatible with the first version of
 Fabric.
 Fabric version 2 is backwards incompatible with version 1:
 http://www.fabfile.org/upgrading.html#upgrading

 And Macports recently saw a bump from version 1.14.0 to version 2.3.1 in
 https://github.com/macports/macports-
 ports/commit/469e4413db27d549576b522b8675838d32809d43
 Which I didn't really paid a lot attention to when upgrading all my ports,
 so suddenly my scripts weren't working anymore. I was luckily able to
 revert to the older version using
 https://trac.macports.org/wiki/howto/InstallingOlderPort
 But when for example a new colleague comes into our company and we have to
 setup his development environment, it will be a bit of a hassle to install
 version 1 of Fabric.

 Therefore the question: would it be possible to maintain a port for both
 version 1 and version 2 of Fabric, to give people the chance to keep
 running their old scripts, until they've got the chance to upgrade them to
 be compatible with v2 of Fabric.

 If this is not technically possible or causes too much hassle, then just
 leave it be.

 Thanks!
