===== Proposal =====
I'd like to see the dialog interface for options replaced. It can not currently handle user defined values or mutually exclusive options easily.

==== Reasons ====
Replacing dialog is beneficial for a number of reasons some of which are listed below
  - Many times some options are mutually exclusive and ports can't indicate as such using the current system 
  - It might be useful to eliminate dialog from the base system (although this isn't a requirement)
  - User defined values could be handled by the options system - instead of only be allowed in make.conf
  - Handles default values from the environment - so default values from /etc/make.conf could be marked.

==== Solved Concerns ====
  - This is not vaporwhere - a prototype exists with some positive feedback so far

==== Unsolved Concerns ====
  * How to implement the binary into bsd.mk.ports
  * How the binary could/should be added to older BSD versions

==== Things the system should do (AKA a spec) ====
  - Provide a system for the ports system to specify different types of options
  - Figure out the default options from the environment
  - Provide the ability to change the values via a menu interface
  - Output the final values in the ports db options format
  - Provide a method to cancel the changes
  - Provide the ability to have some a long helptext 
  - Provide the ability to accept or reject the port's license from the same menu 

==== Implementations and patches ====
  - [[http://isis.poly.edu/~eitan/files/dialog4ports.c|Version 4]]
  - [[https://isis.poly.edu/~eitan/files/d4p-version7/|Version 7]]

==== Ports affected ====
All ports are effected by this change - even if they don't use options
