[etoys-dev] Compressing sources

[Ricardo Moran]

What about using Smalltalk abandonSources as Eliot suggested on squeak-dev?
I just tried with and etoys-dev image and it complained about a syntax error
in MMetaParser>>mExpr so I blindly removed the whole package and tried
again.
It finished without errors and the image seems to be working ok.
