 ** Description: SiSU information Structuring Universe, specialised
    pre-processing wrapper

    sisu -t x_bank.and.*
    e.g. sisu -t x_bank.and.*.termsheet.rb
    e.g. sisu_termsheet.rb -t x_bank.and.c*.termsheet.rb
    program calls upon termsheet file with extension termsheet.rb
    termsheet.rb calls upon relevant standard form files (to be used) with extension .sForm.rb
    there is also a standard_terms.rb file - with terms/details that are  constant
    the file produced is named after the termsheet.rb with that extension replaced with .er30
    from there scribbler.rb is called upon its usual metaVerse html and pdf  creation
    ! :-)
    to test run
    termsheet.rb -f dev.export.import.trade.facility.termsheet.rb
    the term sheet calls the standard form or template that is to be run against it.
