-.SH DESCRIPTION
-.B mount.exfat-fuse
-is a free exFAT file system implementation with write support. exFAT is a
-simple file system created by Microsoft. It is intended to replace FAT32
-removing some of its limitations. exFAT is a standard FS for SDXC memory
-cards.
-
-.SH COMMAND LINE OPTIONS
-Command line options available:
-.TP
-.BI \-d
-Enable debug logging and do not detach from shell.
-.TP
-.BI \-n
-Ignored.
-.TP
-.BI \-o " options"
-File system specific options. For more details see
-.B FILE SYSTEM OPTIONS
-section below.
-.TP
-.BI \-V
-Print version and copyright.
-.TP
-.BI \-v
-Ignored.
-
-.SH FILE SYSTEM OPTIONS
-.TP
-.BI umask= value
-Set the umask (the bitmask of the permissions that are
-.B not
-present, in octal).
-The default is the umask of the current process.
-.TP
-.BI dmask= value
-Set the umask for directories only.
-.TP
-.BI fmask= value
-Set the umask for files only.
-.TP
-.BI uid= n
-Set the owner for all files and directories.
-The default is the owner of the current process.
-.TP
-.BI gid= n
-Set the group for all files and directories.
-The default is the group of the current process.
-.TP
-.BI ro
-Mount the file system in read only mode.
-.TP
-.BI noatime
-Do not update access time when file is read.
-
-.SH EXIT CODES
-Zero is returned on successful mount. Any other code means an error.
