Darryl L. Miles 162db537d8 build: magic/tcltk/scmos/doc/lisp Makefile.in use @srcdir@
Switch the 5 top-level outlier modules to configure-provided substitution
(same template as the rest):
  srcdir   = @srcdir@
  VPATH    = @srcdir@
  MAGICDIR = @top_builddir@
Their custom rules and ${MAGICDIR}/${MAGICSRC} references keep working:
${MAGICDIR} = @top_builddir@ (build top), $(srcdir) now from @srcdir@.
scmos/doc still recurse into their (static) children via -f.

Verified out-of-tree: full `make` rc=0 -- magic gets srcdir=<src>/magic,
tclmagic.so + scmos techs + 27/28 docs build.

README

This is a mini-scheme interpreter, even though the files are all named
lisp*.{c,h}.

This interpreter is *extremely* slow. I can think of lots of ways to
improve its memory usage and performance (a factor of 5 improvement
seems easy), but it is very robust and it works. :) Besides, it turns
out that the bottleneck in most common tasks is magic itself, not the
interpreter.

The memory usage of this interpreter is ridiculously high. Collect garbage
often. :) Garbage collection is done automatically based on the
variable scm-gc-frequency at the top-level . . . i.e., when you see
magic's ">" prompt. To collect garbage at intermediate points in the
computation, you have to call "collect-garbage" explicitly.
