    1.10 +CT_OBSOLETE:
    1.11 +  Show obsolete versions or tools. Most of the time, you don't want to base
    1.12 +  your toolchain on too old a version (of gcc, for example). But at times, it
    1.13 +  can come handy to use such an old version for regression tests. Those old
    1.14 +  versions are hidden behind CT_BSOLETE.

    1.16 +CT_EXPERIMENTAL:
    1.17 +  Show experimental versions or tools. Again, you might not want to base your
    1.18 +  toolchain on too recent tools (eg. gcc) for production. But if you need a
    1.19 +  feature present only in a recent version, or a new tool, you can find them
    1.20 +  hidden behind CT_EXPERIMENTAL.
    1.21 +
    1.22 +CT_BROKEN:
    1.23 +  Show broken versions or tools. Some usefull tools are currently broken: they
    1.24 +  won't compile, run, or worse, cause defects when running. But if you are
    1.25 +  brave enough, you can try and debug them. They are hidden behind CT_BROKEN,
    1.26 +  which itself is hiddent behind EXPERIMENTAL.
