I use a local one-liner shell script that I call "sqcat":

cat $* | tr '\015' '\012'

And another called "sqless"

sqcat $* | less

These are handy for viewing Smalltalk formatted files from the unix
command line.

If I have a scrambled image and want to edit the end of the changes
with a vi editor, I do this:

$ sqcat squeak.changes | tail -4000 > changes.txt

The puts the last 4000 lines of the changes file into a text file
for editing.

When I am ready to to use the text file in Squeak, I use a file
browser and do the "remove line feeds" menu option before using
the file.
