On second thought, I think CURLE_TLSAUTH_FAILED should be eliminated. It
was only being raised when an internal error occurred while allocating
or setting the GnuTLS SRP client credentials struct. For TLS
authentication failures, the general CURLE_SSL_CONNECT_ERROR seems
appropriate; its error string already includes "passwords" as a possible
cause. Having a separate TLS auth error code might also cause people to
think that a TLS auth failure means the wrong username or password was
entered, when it could also be a sign of a man-in-the-middle attack.

"6.7 What are my obligations when using libcurl in my commercial apps?"
got the piece about what exactly "in all copies" mean to a user of the
code.

This interpretation is based on what other MIT-like licenses have made
more explicit.

The default value is 1.

curl _uses_ a default CA bundle, it doesn't install one.

Drop the references to 7.10 as that is now >8 years old!

Extended the intial HTTP protcol part and added a mention of --trace and
--trace-ascii.

Replaced most URLs in the text to use example.com instead of all the
made up strange names.

Shortened a bunch of lines.

Extended the descriptions somewhat and made the options get listed next
to each other.

... and update the curl.1 and curl_easy_setopt.3 man pages such that
they do not suggest to use an OpenSSL utility if curl is not built
against OpenSSL.

Also spelling fix for RECIPIENT #define.

Even if libcurl might to do it for us, it is more correct.

Without this you won't get the next (Subject) line.

This example shows how to send SMTP with TLS

Add a simple SMTP example program, patterned after some of the existing
examples, and the curl application.

This version addresses issues raised by David Woodhouse on comments in
the simplesmtp.c example.
