Where to find e2fsck?

[Kyryll A Mirnenko]

  There's very stupid problem when using EXT2[3]FS partitions read-write on 
FreeBSD that after power failure you have nothing to check it (e.g. 
apropriate fsck) and can't use it rw any more (I've no linux on my machine 
for a year, the partition is one left from it's installation) - kernel denies 
it's mounting rw till it's CLEAR falg is set.
  So, where to find e2fsck for FreeBSD?
  One more question: kernel comments're saying ext2fs support is not updated 
frequently. Is there an alternative ext2fs (and better ext3fs) 3rd party 
support for FreeBSD?
