I've noticed that ./configure --help is inconsistent.

- The way default values are shared
- The way enumerated 
- The verbs used (e.g. enable, set)
- Some --with-xyx and some --with(out-xyz)
- Some start with capitals, others don't

Also, many of the flags could use additional explanation as to their purpose, or reference the rST file in the doc that explains what they do.

Updated version based on principles:

- Should not specify --with(out) in help string
- Sentences should start with lowercase (as autoconf generates the builtin string with lower case)
- --with-xyx=VALUE will be described as "overriding"
- --with-xyz will be described as "enabling" said feature
- Mac flags should have the same descriptions as what is in Mac/README.rst
- default value should be in brackets (if known)
- Enumerated options should be shown as =VAL1|VAL2 or [=VAL1|VAL2] if optional

 Optional Features:
