/* phoon - show the phase of the moon
**
** ver date who remarks
** --- ------- --- -------------------------------------------------------------
** 03B 08oct19 MK Mike Killewald <mkillewald yahoo com>
** Added #ifdef AMIGA (astro.c, date_parse.c, phoon.c)
** Added phasehunt6 (astro.c)
** Added hubert23, pumpkin23 (phoon.c)
** Added parse_args(), parse_amiga_args() (phoon.c)
** Added trim() (phoon.c)
** Added date_calc.c
** Updated putseconds() so it handles negative input (phoon.c)
** Updated putmoon() so tabs line up properly at all times
** 03A 01apr95 JP Updated to use date_parse.
** 02A 07jun88 JP Changed the phase calculation to use code from John Walker's
** "moontool", increasing accuracy tremendously.
** Got rid of SINFORCOS, since Apple has probably fixed A/UX
** by now.
** 01I 03feb88 JP Added 32 lines.
** 01H 14jan88 JP Added 22 lines.
** 01G 05dec87 JP Added random sabotage to generate Hubert.
** Defeated text stuff for moons 28 or larger.
** 01F 13oct87 JP Added pumpkin19 in October. Added hubert29.
** 01E 14may87 JP Added #ifdef SINFORCOS to handle broken A/UX library.
** 01D 02apr87 JP Added 21 lines.
** 01C 26jan87 JP Added backgrounds for 29 and 18 lines.
** 01B 28dec86 JP Added -l flag, and backgrounds for 19 and 24 lines.
** 01A 08nov86 JP Translated from the ratfor version of 12nov85, which itself
** was translated from the Pascal version of 05apr79.
