Hi Igor,
Thanks for your efforts.

The files algebra/*.fasl are the results of compiling Lisp codes generated
from OpenAxiom algebras. As such, they are the heart of the system --
think of them as some of sort DLLs. Every time the interpreter needs
the defnition of a domain (for the purpose of a computation), it
automatically loads the corresponding modules. You can see this by
asking the interpreter to be verbose. Try:
)set message autoload on
factor(x^2 - 3*x + 1)
The extension .fasl is just what SBCL uses to distinguish a FASL from
pure Lisp source code. Every Lisp system has its own FASL format and
they are not interchangeable.

Yes, the FASLs are generally not executable -- they are just binary
files that the Lisp system can load.
The file "interpsys" is executable. It is the main executable we use to
build the OpenAxiom algebra. I suspect that the header that you show
above is SBCL's new way to implement "build a standalone program out of
previously compiled FASLs."

| 1. What is the purpose for these shebangs? Only for building? Or run time?
| 2. May I remove "compiled from ..."?
| 3. Can I completely remove sgebangs? (interpsys is not installed at all)
I think you should not remove them as it is part of the way SBCL does
things, but maybe it is a question for SBCL developers...
Again thanks for your debian efforts.
