These are RCS tags used to identify the revision of the file in question, along with who commited the change and when. RCS is used by the FreeBSD community (in the form of CVS) to manage changes to the source code, and RCS in turn uses '$' to surround special identifiers that get expanded when the file is checked out or exported from the repository. The 'Exp' on the end is an RCS state value which denotes 'Experimental', however this can be ignored as it is not used. You can also use the 'ident' command to extract these strings from a binary file to determine which version of the source code it was compiled from.
