.SH DESCRIPTION
.I Hget
retrieves the web page specified by the URL
.I url
and writes it, absent the
.B -o
option, to standard output.
.PP
The
.I url
can be a relative path like
.B ../index.html
if a absolute
.I baseurl
was specified with the
.B -b
option.
.PP
If
.I url
is of type HTTP and the
.B -p
or
.B -P
options are specified, then a HTTP POST is performed.
With
.B -p
the data to be posted is provided by the
.I body
argument as a string or alternatively with
.B -P
read from standard input.
.PP
The
.B -o
option is used to keep a local file in sync with a
web page.  If the web page has been modified later than the
file, it is copied into the file.  If the file is up to date
but incomplete,
.I hget
will fetch the missing bytes.
.PP
Option
.B -r
sends an arbitrary HTTP
.IR header .
.PP
Option
.B -m
overrides the HTTP method used for the request.
.PP
.I Formpost
retrieves the web page specified by the URL
.I url,
parses its HTML for form data, then prints
.I hget
commands to submit forms to the
.I url.
If the
.B -M, -g, -p
or
.B -m
flags are set, the
.I hget
commands are assembled without first retrieving and interpreting the
target HTML.
.PP
If the
.B -d
flag is specified, debugging information is written
to the file
.B formpost.log
in the current directory.
.PP
The
.B -M
flag applies multipart/form-data encoding to the
remaining arguments and prints the result on
the standard output.
.PP
The
.B -u
flag sets the target URL to
.I url.
.PP
The
.B -g
and
.B -p
flags set the the form method to GET and POST, respectively. The
.B -m
flag sets the form method to POST and its enctype to multipart/form-data.
In all cases, the form action is set to
.I action.
.PP
The remaining arguments of the form
.B name:value
are interpreted as form field names and values to be submitted along
with the form. An argument of the form
.B name:@value
is interpreted as a file upload, with the information following the
.B @
symbol treated as the full path to the location of the file.
.SH EXAMPLES

.I hget
command needed to submit a form, which may then be
