faq fodder: best way to...?

[thi <ttn at revel dot glug dot org>]

- enable a #!guile script to start an interactive debug shell on error
- display or log script "commands" (a la /bin/sh -x)
- augment `%load-path' from outside guile scheme (setting env var
  clobbers `%load-path', does not pre/post-pend)
- invoke script w/o using hardcoded /full/path/to/guile

hopefully someone can answer these and they will be recorded in the faq
or cookbook section or both.  btw, i saw something (sorry, forgot where)
like

	":"; exec guile "$@"

for the last answer that seemed pretty interesting.
