output from a package

During a Mathematica session I developed a set of algebraic equations to solve a problem describing the vapor-liquid equilibrium in a reactor. The procedure I used was to define the equations, define a set of rules defining the parameters, define a set of initial conditions, then get the equations and initial conditions in a form that FindRoot likes and call the function. FindRoot returns the set of rules at the solution.

Now I want to carry out the calculation a number of times so I used the package template from Maeder's book to turn my notebook into a package. The calculations work as expected, but the values returned from FindRoot are in the context of the package, e.g.

{vlepackage`Private`wC2->.....}

There are many variables, so I prefer to set up the definition to use the same names every time. What I would like is something like the `Statistics`LinearRegression package that always returns a rule with a name from the current context (or that what it looks like)

That is I would like to be able to say things like

wC2/.vlecalculation[p1,p2,p3]

and the module would return a rule list that would work.

Is there an straightforward way to do this?

Thanks

Steve
