No, I actually meant "declarative" .... See this reference:

Quote:

In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow. Many languages applying this style attempt to minimize or eliminate side effects by describing what the program should accomplish, rather than describing how to go about accomplishing it. This is in contrast with imperative programming, which requires an explicitly provided algorithm.

Declarative programming often considers programs as theories of a formal logic, and computations as deductions in that logic space. Declarative programming has become of particular interest recently, as it may greatly simplify writing parallel programs.

Common declarative languages include those of regular expressions, logic programming, and functional programming.

I see now that Ruby is not classified as a "declarative programming language", List of programming languages by category.

LEARN ABOUT DEBIAN

dh-make-ruby

DH-MAKE-RUBY(1) 														   DH-MAKE-RUBY(1)

NAME

       dh-make-ruby - build Debian source package from Ruby library

USAGE

       dh-make-ruby [OPTIONS] TARBALL|DIRECTORY

DESCRIPTION

       dh-make-ruby will create a basic Debian source package from a tarball named TARBALL generated with gem2tgz, or from a DIRECTORY containing
       Ruby code and metadata in a .gemspec file.

OPTIONS

       -p PACKAGE, --package PACKAGE
	   Uses PACKAGE as package name. By default, new packages will be named as ruby-$gem, where $gem is the upstream name. If the package is
	   mainly used as a library, then it should use the default. On the other hand, if the packages is mainly used as an application, then you
	   should drop the ruby- prefix by using this option an explicit package u.

       --ruby-versions VERSIONS
	   Ruby versions to build the package for. This is used to generate the X-Ruby-Versions: field in the source package, that can later be
	   used to tune this value.  By default, gem2deb generates a package that works on all known Ruby versions, but it might be necessary to
	   only build the package for Ruby 1.8, for example (using --ruby-versions "ruby1.8").

       -h, --help
	   Displays the help

       -v, --version
	   Displays version information and exits.
