 C.2 The cvswrappers file
 ========================
 
 Wrappers refers to a CVS feature which lets you control certain
 settings based on the name of the file which is being operated on.  The
 settings are `-k' for binary files, and `-m' for nonmergeable text
 files.
 
    The `-m' option specifies the merge methodology that should be used
 when a non-binary file is updated.  `MERGE' means the usual CVS
 behavior: try to merge the files.  `COPY' means that `cvs update' will
 refuse to merge files, as it also does for files specified as binary
 with `-kb' (but if the file is specified as binary, there is no need to
 specify `-m 'COPY'').  CVS will provide the user with the two versions
 of the files, and require the user using mechanisms outside CVS, to
 insert any necessary changes.
 
    *WARNING: do not use `COPY' with CVS 1.9 or earlier - such versions
 of CVS will copy one version of your file over the other, wiping out
 the previous contents.* The `-m' wrapper option only affects behavior
 when merging is done on update; it does not affect how files are
 stored.  See  Binary files, for more on binary files.
 
    The basic format of the file `cvswrappers' is:
 
      wildcard     [option value][option value]...
 
      where option is one of
      -m           update methodology      value: MERGE or COPY
      -k           keyword expansion       value: expansion mode
 
      and value is a single-quote delimited value.
 
    For example, the following command imports a directory, treating
 files whose name ends in `.exe' as binary:
 
      cvs import -I ! -W "*.exe -k 'b'" first-dir vendortag reltag
