"""
|
|
There are several things here:
|
|
- a different command-line option management making options persistent
|
|
- the review command to display the options set
|
|
|
|
Assumptions:
|
|
- configuration options are not always added to the right group (and do not count on the users to do it...)
|
|
- the options are persistent between the executions (waf options are NOT persistent by design), even for the configuration
|
|
- when the options change, the build is invalidated (forcing a reconfiguration)
