# Configurations
|
|
#
|
|
# The following class helps to manage toolset configurations. Each configuration
|
|
# has a unique ID and one or more parameters. A typical example of a unique ID
|
|
# is a condition generated by 'common.check-init-parameters' rule. Other kinds
|
|
# of IDs can be used. Parameters may include any details about the configuration
|
|
# like 'command', 'path', etc.
|
|
#
|
|
# A toolset configuration may be in one of the following states:
|
|
#
|
|
# - registered
|
|
# Configuration has been registered (e.g. explicitly or by auto-detection
|
|
# code) but has not yet been marked as used, i.e. 'toolset.using' rule has
|
|
# not yet been called for it.
|
|
# - used
|
|
# Once called 'toolset.using' rule marks the configuration as 'used'.
|
|
#
|
|
# The main difference between the states above is that while a configuration is
|
|
# 'registered' its options can be freely changed. This is useful in particular
|
|
# for autodetection code - all detected configurations may be safely overwritten
|
|
# by user code.
