Can anyone explain the difference between the two Sun assemblers 'fbe'
and 'as'? Aside from the fact that fbe comes with Sun Studio and as is
bundled in /usr/ccs/bin, that is. I'm trying to figure out someone
else's old build system and I see that some assembler code is built with
one and some with the other. Neither one's man page mentions the other
and I can find no docs on the web contrasting them. It does look like
the fbe man page is adapted from as, because fbe mistakenly refers to
itself as 'as' in several places.
