    • Package Flags

      tagged
       (on by default)

      You can disable the use of the tagged package using `-f-tagged`.

      Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users.

      semigroups
       (on by default)

      You can disable the use of the semigroups package using `-f-semigroups`.

      Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users.

      safe
       (off by default)

      Get Safe guarantees rather than merely Trustworthy, but with worse constant factors.

      statevar
       (on by default)

      You can disable the use of the StateVar package using `-f-StateVar`.

      Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users.
