>From this I gather your answer is "yes" this is what you want to do.  I suppose
you have a lot more confidence in the tools than I do.  I think we will get bit
by this someday, but I have nevertheless done what you want.  We now have all
separate algorithm packages.  However, I decided against Monticello prereqs;
one change to Base and you suddenly have to resave *eleven* packages, and we
all know how buggy prereqs are.  But I'll go any direction the team wants to on
this..

I follwed hmm's lead on removing ASN1Constants pool dictionary, it was causing
a load warning, but not sure whether it was needed or not.  I know nothing
about ASN1.  Further, I noticed some of the base-class extensions named
"decodeAsn1Der" were also used by DSA.  Therefore, ALL ASN1 extensions are in
the CryptographyBase package.  Someone who knows about ASN1 should clean this
up.

Remember, you need to load CryptographBase-cmm.3.mcz, NOT version 5.  Also,
Cryptography-Support is not needed.

After you load Base.3, then load each algorithm-specific package and, finally,
the Tests package.  15 of 18 of the tests pass, just as if I load Cryptography
0.3 from SqueakMap.
