.SH DESCRIPTION
.I Httpfile
serves the web page specified by the URL
.I url
as a new file
.I file
in the directory
.IR mtpt .
The default
.I file
is the last path element of the URL,
and the default
.I mtpt
is the current directory.
.PP
.I Httpfile
does not download large files all at once.
Instead, it requests 64-kilobyte blocks as they are
needed to satisfy reads, caching a few blocks in memory at a time.
.PP
The 
.B -D
and
.B -d
options enable a trace of the 9P traffic
and general debugging messages.
.PP
The
.B -s
option causes 
.I httpfile
to post the 9P service as
.BI /srv/ srvname
and disables the default mount.
.PP
The
.B -x
option specifies an alternate network directory
.RI ( e.g., 
.BR /net.alt ).
.PP
The
.B -b
option sets the number of file blocks kept cached in memory (default 32).
