c4 -- searches for changes (like CVS), import file trees
Import or re-import whole file trees with correct add/edit/delete
operations; Search for modified/new/removed files
and do the correct
edit/add/delete operations (inspired by CVS).
C4 was originally created to give p4 a CVS feel, by allowing
perforce clients to have writable files, and have c4 locate
changed files in a way similar to CVS.
This has been expanded
to correctly find arbitrary changes between the current top of
tree and the client so that whole trees can be imported.
This is routinely used to import updates to
external source, including
updates that can remove/rename whole directories of files.
C4 provides a control file that is placed at the top of
each client to set environment variables, such as
(p4 now provides this also).
C4 is not public domain; it is provided free of charge under
a license similar to the Berkeley UNIX license,
such as that used in FreeBSD.
