......@@ -12,9 +12,15 @@ This file requires cl-launch 4 and works on most implementations.
It notably doesn't work on:
* ABCL, that keeps ASDF in its jar, but that's OK because
ABCL has a recent enough ASDF3 that is capable of upgrading itself.
* On MKCL and ECL, more work is needed to take into account
the linkable variant of ASDF, that may be a .o or a .lib.
Also, MKCL now delivers UIOP separately from ASDF, which is great,
but requires support. Happily, both ECL and MKCL tend to sport
a recent ASDF 3, too.
* GCL, that doesn't have a usable REQUIRE mechanism.
* mocl, that doesn't support ASDF 3 yet.
* Corman Lisp, RMCL, Genera, that are obsolete anyway.
