curl is not an interactive program and uses a different means to specify
which files to upload and download. It supports the --config option which
takes options from a file, so in that sense you can call curl in the same
manner. But the contents of the file will be completely different.

That's not how curl works. It operates on URLs, so rather than manually
changing directories and pushing and pulling files, you just specify
the URLs and curl will do all the cd and mkdir commands automatically for
you.

That's how curl works, so if you want to switch tools, you'll have to rewrite
your scripts. It should be pretty simple to automate a conversion from the
style you're using to curl's style, though. Another alternative is to use
an SSL-enabled ftp client, like the one in Linux Netkit. That might even
be plug-and-play compatible with your scripts as written.
