annotate lwasm/symbol.c @ 467:a6c9129e5948

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Move version header into a common direction to better reflect what it is. The version header isn't really associated with lwlib itself since that is intended to be some generic type routines that can be used by other programs. It is, however, directly associated with lwtools. Thus, it should be related to lwtools itself rather than the more generic lwlib.
