I have recently tagged a v0.2.0 release of pimsync. From the changelog:

• Attempt to use the provided URL before doing service discovery. If the URL provided in the configuration file is a valid context URL for a DAV server, discovery is skipped entirely.
• Fixed some erroneous handling of percent-encoded characters in URLs.
• Prompt early for all required credentials. This speeds up start-up, since there’s no network IO between prompts.
• Several documentation improvements.
• Reject configuration file on superfluous parameter.

A minimal website is now available, and the documentation is now available online too, all at https://pimsync.whynothugo.nl/.
