How I program in Scheme
-----------------------

When looking for library functions, I use the following search order
to keep what I learn and my code most portable across Scheme
implementations.

- search in the R5RS Scheme spec
- search the SRFIs and then check whether my Scheme implements the
  SRFI found
- search SLIB
- use a Scheme implementation specific library function
