[GNUnet-SVN] [gnurl] 118/254: curl: generate the --help output

[gnunet]

This is an automated email from the git hooks/post-receive script.

ng0 pushed a commit to annotated tag gnurl-7.54.1
in repository gnurl.

commit 8b2f22ed29dc06eb55941c82c6ee48bdd7542487
Author: Daniel Stenberg <address@hidden>
AuthorDate: Mon May 8 23:30:29 2017 +0200

    curl: generate the --help output
    
    ... using the docs/cmdline-opts/gen.pl script, so that we get all the
    command line option documentation from the same source.
    
    The generation of the list has to be done manually and pasted into the
    source code.
    
    Closes #1465
