This directory contains a couple of small scripts that show how to do 
algorithms with recursive 'dc' macros.  The scripts are listed below.

  o exp.dc - bit of code that can compute logarithms and fractional exponents
  o birthday.dc - compute the 'birthday paradox' probability for two numbers.
                  Call the script for the Wikipedia example in the following
                  manner: dc -f birthday.dc -e'365 23 lfx'
                  Result:  50.729800
  o sum.dc - compute the sum for i=1 -> of 1/i.
             Call the script in the following way: dc -f sum.dc -e'1000 lsx p'
             Result:  9.3668

  o simple model for estimating the cost of a release
           Call the script in the following way:
              dc -f releasecost.dc -e'numemployees_in_org percentage_of_employees_on_other_projects percentage_of_time_remaining_employees_spend_on_other_commitments periodic_budget number_of_periods'
           Result:  a dollar amount
           
               
      
Advice for people scripting 'dc':
    o don't fight using registers in some ideological effort to only use the
      stack.  You are not using Forth.
    o liberally sprinkle 'f' into your code to inspect the stack.
    o the code will be short but your comments probably shouldn't be.
    o test your snippets of code in tiny pieces and assemble the script
      incrementally.
    o it's addicting and feels vaguely like fun instead of work.
