     ctm — source code mirror system

     The ctm transfers data in a specific file format, called a CTM delta.

     CTM deltas consist of control lines and data chunks.  Each control line
     starts with the letters “CTM”, followed by a CTM statement and control
     data, and ends with a '\n' character.

     Data chunks always belong to the preceding control line, and the last
     field on that control line is the number of bytes in the data chunk.  A
     trailing newline '\n' character follows each data chunk, this newline is
     not part of the chunk and is not included in the count.

     The CTM statements are as follows.

     _BEGIN version name number timestamp prefix
	     This is the overall begin of a CTM delta file.  The version field
	     must match the program version (currently 2.0).  Name is the name
	     and number the sequence number of the CTM service, it is matched
	     against the file .ctm_status to see if the delta has already been
	     applied.  Timestamp contains the year, month, day, hour, minute,
	     and second of the time of delta creation for reference (followed
	     by the letter ‘Z’ meaning this is a UTC timestamp).  The prefix
	     field is currently not implemented.

     _END md5
	     This statement ends the CTM delta, the global md5 checksum is
	     matched against the MD5 checksum of the entire delta, up to and
	     including the space (0x20) character following ``_END''.

     FM name uid gid mode md5 count
	     Make the file name, the original file had the uid uid (numerical,
	     decimal), the gid gid (numerical, decimal), mode mode (numerical,
	     octal), and the MD5 checksum md5.

	     The following count bytes data are the contents of the new file.

     FS name uid gid mode md5before md5after count
	     Substitute the contents of file name, the original file had the
	     new uid uid (numerical, decimal), the new gid gid (numerical,
	     decimal), new mode mode (numerical, octal), the old MD5 checksum
	     md5before, and the new MD5 checksum md5after.

	     The following count bytes data are the contents of the new file.

	     File substitution is used if the commands to edit a file would
	     exceed the total file length, so substituting it is more effi‐

     FN name uid gid mode md5before md5after count
	     Edit the file name.  The arguments are as above, but the data
	     sections contains an diff(1) -n script which should be applied to
	     the file in question.

     FR name md5
	     Remove the file name, which must match the MD5 checksum md5.

     AS name uid gid mode
	     The original file name changed its owner to uid, its group to
	     gid, and/or its mode to mode.

     DM name uid gid mode
	     The directory name is to be created, it had originally the owner
	     uid, group gid, and mode mode.

     DR name
	     The directory name is to be removed.

     In the following example, long lines have been folded to make them print‐
     able (marked by backslashes).

     Initial trials ran during the FreeBSD 1.1.5, and many bugs and methods
     were hashed out.  The CTM system has been made publicly available in
     FreeBSD 2.1.

     The CTM system has been designed and implemented by Poul-Henning Kamp
