Eric:
This is extremely useful. I found some documentation on the site, re the
API. I am way over my head here, but I need (for one) data on Lunar
Declination over, say, a year, but really month-by-month. Is there a "for
Dummies" to get this data off of this server? A cookbook? Can I do
something like this?
grep -E 'oon&&eclin' >${tmpfile}
?
Thank you again.

[Fill in the blanks]
The use of corrupt manipulations and blatant rhetorical ploys ...---
outright lying, flagwaving, personal attacks, setting up phony
alternatives, misdirection, jargon-mongering, evading key issues, feigning
disinterested objectivity, willful misunderstanding of other points of
view---suggests that ... lacks both credibility and evidence.
