Scheme Requests for Implementation (SRFIs), as R6RS libraries
-------------------------------------------------------------

The libraries' names conform to SRFI 97: SRFI Libraries.  There is a registry of
available SRFIs and other platform features which works alongside SRFI 0:
Feature-Based Conditional Expansion.  The porting done so far is mostly just
taking the reference implementations from http://srfi.schemers.org and wrapping
them in libraries and tweaking the few things needed to make them work in R6RS
libraries and with implementations' functionality.  Supporting any R6RS
implementation supporting the *.IMPL.sls convention is easy.

These SRFIs are available:
  (srfi s0 cond-expand)
  (srfi s1 lists)
  (srfi s2 and-let)
  (srfi s5 let)
  (srfi s6 basic-string-ports)
  (srfi s8 receive)
  (srfi s9 records)
  (srfi s11 let-values)
  (srfi s13 strings)
  (srfi s14 char-sets)
  (srfi s16 case-lambda)
  (srfi s17 generalized-set!)
  (srfi s19 time)
  (srfi s23 error)
  (srfi s25 multi-dimensional-arrays)
  (srfi s26 cut)
  (srfi s27 random-bits)
  (srfi s28 basic-format-strings)
  (srfi s31 rec)
  (srfi s37 args-fold)
  (srfi s38 with-shared-structure)
  (srfi s39 parameters)
  (srfi s41 streams)
  (srfi s42 eager-comprehensions)
  (srfi s43 vectors)
  (srfi s45 lazy)
  (srfi s48 intermediate-format-strings)
  (srfi s60 integer-bits)
  (srfi s61 cond)
  (srfi s64 testing)
  (srfi s67 compare-procedures)
  (srfi s69 basic-hash-tables)
  (srfi s78 lightweight-testing)
  (srfi s89 optional-parameters)
  (srfi s98 os-environment-variables)
  (srfi s99 records)
  (srfi s111 boxes)
  (srfi s143 fixnums)

NOTE: We use 's' instead of ':' because files with ':' are not supported in
Windows.
NOTE2: SRFI 89 is implemented using symbols ending in ':' as keywords, which
need to be quoted. This is not fully compliant with the standard.

Other SRFIs are not available because there hasn't been a demand for them or
they're not possible as an R6RS library.  If you already have ported SRFIs to
R6RS, we'd love to assimilate them.  You can let us know by "asking a question"
at the Scheme Libraries project page:

  https://launchpad.net/scheme-libraries

Currently supported systems are Chez Scheme, Ikarus, Larceny, and Ypsilon.
PLT Scheme is only semi-supported because it has its own "srfi" directory
which conflicts with having another "srfi" directory; you can symlink/copy
files from this collection into PLT's "srfi" directory.
