[Boost-users] [program_options] multi-line options

Vladimir,

I tried escaping line breaks in a config file with '\' but to no avail.

Is there any way of specifying options over multiple lines?

Would this be something you would consider as an enhancement to
boost::program_options?

Thanks,
James

Yes, that method was removed on 2005-04-22. The motivation is that it
just
leads to parsing ambiguities and no good command line interface I ever
seen
uses optional values.
