this is obviously right.
{{{rem}}} means that the whole line is commented out, same as {{{#}}} for
Unix shells.
Indeed, this line can be deleted (a debugging leftover).

{{{C:\cygwin\bin\dash.exe}}} in the command prompt would not be amiss,
the batch file does the right thing, if your Cygwin is in {{{C:\cygwin}}}.
Otherwise the corr. line there needs to be changed.
>since one could imagine people helping who don't know how to set paths in
Windows, or even how to make env vars in Windows (e.g., I have no idea how
to set `SAGE_ROOT` in the Windows command line).
no, it is meant to be changed in the batch file body. Perhaps I should
mention that it is meant to call the dash script from the batch file, and
not directly.
By the way, setting {{{BLAH}}} to {{{foo}}} in the Windows command line is
just
{{{
set BLAH=foo
}}}
And if you need to evaluate {{{BLAH}}} you do {{{%BLAH%}}}, e.g.
{{{
echo %BLAH%
}}}
will print {{{BLAH}}}'s value. You might also want to know that if you
call dash after setting {{{BLAH}}}, it will be known to dash, and can be
evaluated as usual, i.e. as {{{$BLAH}}}. dash will also treat {{{PATH}}}
in a special way, by trying to translate it into Cygwin's PATH in some
cases. But I digressed. :-)
