Each control line starts with the letters .Dq CTM , followed by a CTM statement and control data, and ends with a '\en' character. .Pp 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 '\en' character follows each data chunk, this newline is not part of the chunk and isn't included in the count. .Pp The CTM statements are as follows. .Bl -tag -width indent .It _BEGIN Ar version name number timestamp prefix This is the overall begin of a CTM delta file. The .Ar version field must match the program version (currently 2.0). .Ar Name is the name and .Ar number the sequence number of the CTM service, it is matched against the file .Pa .ctm_status to see if the delta has already been applied. .Ar Timestamp contains the year, month, day, hour, minute, and second of the time of delta creation for reference (followed by the letter .Sq Z meaning this is a UTC timestamp). The .Ar prefix field is currently not implemented. .It _END Ar md5 This statement ends the CTM delta, the global .Ar md5 checksum is matched against the MD5 checksum of the entire delta, up to and including the space (0x20) character following ``_END''. .It \&FM Ar name uid gid mode md5 count Make the file .Ar name , the original file had the uid .Ar uid (numerical, decimal), the gid .Ar gid (numerical, decimal), mode .Ar mode (numerical, octal), and the MD5 checksum .Ar md5 . .Pp The following .Ar count bytes data are the contents of the new file. .It \&FS Ar name uid gid mode md5before md5after count Substitute the contents of file .Ar name , the original file had the new uid .Ar uid (numerical, decimal), the new gid .Ar gid (numerical, decimal), new mode .Ar mode (numerical, octal), the old MD5 checksum .Ar md5before , and the new MD5 checksum .Ar md5after . .Pp The following .Ar count bytes data are the contents of the new file. .Pp File substitution is used if the commands to edit a file would exceed the total file length, so substituting it is more efficient. .It \&FN Ar name uid gid mode md5before md5after count Edit the file .Ar name . The arguments are as above, but the data sections contains an .Xr diff 1 -n script which should be applied to the file in question. .It \&FR Ar name md5 Remove the file .Ar name , which must match the MD5 checksum .Ar md5 . .It \&AS Ar name uid gid mode The original file .Ar name changed its owner to .Ar uid , its group to .Ar gid , and/or its mode to .Ar mode . .It \&DM Ar name uid gid mode The directory .Ar name is to be created, it had originally the owner .Ar uid , group .Ar gid , and mode .Ar mode . .It \&DR Ar name The directory .Ar name is to be removed. .El .Sh EXAMPLES In the following example, long lines have been folded to make them printable (marked by backslashes). .Bd -literal CTM_BEGIN 2.0 cvs-cur 485 19950324214652Z .
