19# Usage:
20#   mmimportfs {Device|all} -i ImportfsFile [-S ChangeSpecFile] [-R]
21#
22# where
23#   Device        is the file system to be imported.
24#                 If Device is "all", then all file systems in
25#                 the input file are imported.  Free disks, if any,
26#                 are imported as well.
27#                 Note:  To request a file system with the name "all",
28#                        specify "/dev/all" to distinguish from the
29#                        keyword "all" (import all file systems).
30#
31#   -i ImportfsFile   is the name of a file with the file system
32#                     information.  It must be created by mmexportfs.
33#
34#   -S ChangeSpecFile  a file containing a detailed description of changes
35#                 to be made to the file systems during the import step.
36#
37# Undocumented option:
38#
39#   -R            remove the specified file system from the mmsdrfs file
40#                 and replace it with the data from the import file.
41#                 If 'all' is specified, all file system and free disk
42#                 information that may currently exist is removed from
43#                 the mmsdrfs file and is replaced with the data from
44#                 the import file.
