Pilot-link is a command line tool set that lets you synchronize your palm device with your linux PC. I currently use a treo and it works pretty well with it. Pilot-link is not a new tool. It has been around for around 10 years. There are plenty of tools to synchronize your palm devices with linux. I used some of them and I can tell that jpilot is pretty more stable than kpilot or gnome-pilot. When you use your palm with the usb craddle, interaction with the PC is not that automatic with jpilot in ubuntu. You need to press the hotsync button and then run the hotsync in jpilot. After that, it synchronizes pretty well.
Other useful tools pilot-link provides are: pilot-addresses, pilot-datebook, pilot-xfer and dlpsh. dlpsh is nice. It gives you a shell in which you can perform a set of basic operations on your palm device.
There are various code samples, modules and programs to parse pdb database files. A very useful one is the perl module PDB.pm. pilot-link also provides special functions to be used from your C programs.
