.SH NAME

curl \- transfer a URL

.SH SYNOPSIS

Specify the filename as '-' to make curl read the file from stdin.

Note that to be able to specify a URL in the config file, you need to specify

it using the --url option, and not by simply writing the URL on its own

line. So, it could look similar to this:

url = "http://curl.haxx.se/docs/"

This option can be used multiple times.

.IP "-l/--list-only"
