# c4 -- searches for changes (like CVS), import file trees

Neil Russell

Synopsis:
  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).

Description:
  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 `P4PORT` and `P4CLIENT` (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.
