32 | # Configurations | |
33 | # | |
34 | # The following class helps to manage toolset configurations. Each configuration | |
35 | # has a unique ID and one or more parameters. A typical example of a unique ID | |
36 | # is a condition generated by 'common.check-init-parameters' rule. Other kinds | |
37 | # of IDs can be used. Parameters may include any details about the configuration | |
38 | # like 'command', 'path', etc. | |
39 | # | |
40 | # A toolset configuration may be in one of the following states: | |
41 | # | |
42 | # - registered | |
43 | # Configuration has been registered (e.g. explicitly or by auto-detection | |
44 | # code) but has not yet been marked as used, i.e. 'toolset.using' rule has | |
45 | # not yet been called for it. | |
46 | # - used | |
47 | # Once called 'toolset.using' rule marks the configuration as 'used'. | |
48 | # | |
49 | # The main difference between the states above is that while a configuration is | |
50 | # 'registered' its options can be freely changed. This is useful in particular | |
51 | # for autodetection code - all detected configurations may be safely overwritten | |
52 | # by user code. | |
