As part of all the project work we are doing at CRT, we have migrated simpleRETS over to Google’s project hosting. We have also renamed the project REsync.
For those that are unfamiliar with REsync (aka simpleRETS), it is a simple command line RETS client that is easy to setup and run. It outputs RETS data to CSV format for easy import into many tools and can be run easily from a scheduling program. It allows you to browse the RETS metadata, download data as well as objects such as photos. Take a look at the project page to get a good idea of what REsync does.
The first release for REsync under the new name went also out today, REsync version 1.5.
