+Metafiles
+=========
+
+Metafiles are used to let a filesystem builder, such as mkcramfs and
+mkfs.jffs2, ignore files and change attributes of files while building
+the filesystem.
+
+This document briefly describes how Axis Communications are using metafiles
+with mkcramfs amd mkfs.jffs2 and is also a proposal of a metafile standard
+for filesystem builders.
+
+
+
+Metafile Format
+===============
+
+An instruction is a line in a metafile telling the filesystem builder if
+anything special should be done with a file or directory before writing it to
+the filesystem. The following instructions should be recognized by the
+filesystem builder:
+
+
+Ignore
+------
+Syntax: "Ignore: FILE"
+
+Ignores a file or directory. I.e. FILE is not included in the filesystem.
+The metafiles themselves are always ignored and do not have to be mentioned
+in any metafiles.
+
+
+IgnoreContents
+--------------
+Syntax: "IgnoreContents: DIRECTORY"
+
+Ignores the contents of a directory. I.e. DIRECTORY is included in the
+filesystem but all files and directories in DIRECTORY are ignored.
+
+
+Include
+-------
+Syntax: "Include: FILE"
+
+Includes a file or directory. If an Include instruction is found in a
+metafile, all files or directories (in the same directory as the metafile)
+that are not included will be ignored (NOTE!).
+
+
+Device
+------
+Syntax: "Device: FILE TYPE MAJOR MINOR"
+
+Convert a regular file to a device special file. If FILE exists it will be
+written to the filesystem as a character or block special file with
+MAJOR and MINOR numbers. TYPE is 'b' for block and 'c' for character device.
+
+Example: To create the character special file /dev/ttyS0 using metafiles,
+add the following line to the metafile in the /dev directory:
+
+Device: ttyS0 c 4 64
+
+
+UserId
+------
+Syntax: "UserId: FILE UID"
+
+Change file owner. The owner of FILE will be UID.
+
+
+DefaultUserId
+-------------
+Syntax: "DefaultUserId: UID"
+
+Change file owner recursively. All files and directories in this directory
+will be owned by UID unless overridden with the UserId instruction.
+
