97+Amiga SmartFileSystem, Linux implementation
98+===========================================
99+
100+This is a simple read-only driver. It support reading files and directories.
101+Symbolic links (called soft links) are not supported yet. Don't even try
102+to read them.
103+
104+
105+Mount options for the ASFS
106+==========================
107+
108+setuid[=uid]
109+ This sets the owner of all files and directories in the file
110+ system to uid or the uid of the current user, respectively.
111+
112+setgid[=gid]
113+ Same as above, but for gid.
114+
115+mode=mode
116+ Sets the mode flags to the given (octal) value. Directories
117+ will get an x permission if the corresponding r bit is set.
118+ The default mode is 0444, which means all r bits are set
119+ (for directories this means also that all x bits are set).
120+
121+
122+Other information
123+=================
124+
125+Supported block sizes are: 512, 1024, 2048 and 4096 bytes. Larger blocks
126+speed up almost everything at the expense of wasted disk space. The speed
127+gain above 4K seems not really worth the price, so you don't lose too
128+much here, either.
129+
130+This file system hasn't been well tested yet. Athough it CANNOT destroy
131+your data, it MIGHT cause a crash. Sorry.
132+
133+This file system has been tested on Motorola PPC and Intel x86 systems.
134+It SHOULD also work on Motorola 68k. It probably WON'T work on other
135+systems (especially 64bit).

6722+ *
6723+ * v0.1beta (11.06.2003)
