This means 'mspA depends on usermspA' and 'usermspA depends on mspA'.
ACD expressly forbids this. All dependencies must be to something defined
earlier in the file.

Could be done with an extra ACD attribute, with a value of "$(usermspA)",
but you would expect most GUIs to ignore this.

In general, you can expect to have options in EMBOSS that are not used by
the program but can still be set on the command line. Your -mspA is just
another case.

Having said that, adding an ACD function (you would only need one) to test
whether a value was set by the user is fairly trivial (setting via the
command line or by replying to a prompt if there is one).
