Conversion to FreeBSD from Linux

[Scott St. John]

I have been searching the net for a simple answer and I will continue to
look, but if anyone has a link, please pass it along.

Two years ago I converted my BSDi password file to Linux with a simple
script to replace fields.  For obvious reasons I want to move back to
FreeBSD, but of course I need to convert the Linux passwd file of 2,000+
users to FreeBSD.

Any links will be appreciated!

Thank you,
