Yes

Text processing (awk etc.), process control

The above

The rest.

Yes, it's a pain going Scheme48 <---> MzScheme

My fellow Schematicians have ported SRFI 13 and 14 to
PLT Scheme (CVS, srfi/) which puts you a long way
towards supporting the text processing stuff.  There
is also a semi-port of some of the text processing
stuff (CVS, data/).  The main funkiness is the
Scheme48 macros (let-optional, receive) that are used
extensively in the code.  We have implementations of
them (srfi/optional.ss) but it is probably more
efficient to replace them with their PLT equivalents
(case-lambda etc.)
