.B CURLOPT_NETRC
-A non-zero parameter tells the library to scan your \fI~/.netrc\fP file to
-find user name and password for the remote site you are about to access. Only
-machine name, user name and password is taken into account (init macros and
-similar things aren't supported).
+This parameter controls the preference of libcurl between using user names and
+passwords from your \fI~/.netrc\fP file, relative to user names and passwords
+in the URL supplied with \fICURLOPT_URL\fP.

+\fBNote:\fP libcurl uses a user name (and supplied or prompted password)
+supplied with \fICURLOPT_USERPWD\fP in preference to any of the options
+controlled by this parameter.

+.B CURL_NETRC_OPTIONAL
+The use of your \fI~/.netrc\fP file is optional,

+to find the first user name and password after that \fImachine\fP,
+which ever information is not specified in the URL.

+This value tells the library that use of the file is required,
