# Within all directories, remove things which don't look like source
# files. Some explanations:
#   sbcl
#     the runtime environment, created by compiling C code
#   sbcl.h
#     information about Lisp code needed to build the runtime environment,
#     created by running GENESIS
#   Config, target
#     architecture-dependent or OS-dependent symlinks
#   core
#     probably a Unix core dump -- not part of the sources anyway
#   *.o, *.so, *.lib, *.nm, a.out
#     results of C-style linking, assembling, etc.
#   *.core, *.map
#     looks like SBCL SAVE-LISP-AND-DIE or GENESIS output, and
#     certainly not source
#   *~, #*#
#     common names for editor temporary files
#   TAGS, tags
#     files created by GNU etags and ctags
#   .#*, *.orig, .*.orig, *.rej
#     rubbish left behind by CVS updates
#   *.htm, *.html
#     The system doc sources are mostly texinfo, plus various odds
#     and ends like docstrings embedded in .lisp sources; any HTML is
#     automatically-generated output.
#   depend, *.d
#     made by "make depend" (or "gmake depend" or some such thing)
#   *.lisp-obj, *.fasl, *.x86f, *.axpf, *.lbytef, *.lib
#     typical extensions for fasl files (not just from SBCL, but
#     from other Lisp systems which might be used as xc hosts)
#   *.tmp, *.lisp-temp
#     conventional names for temporary files autogenerated in
#     building or testing
