Remind is a sophisticated command-line calendar and alarm program
with a sophisticated scripting language and intelligent handling of
exceptions and holidays.

There are several options to pass to this script at compile-time.
Some of these options can be changed at run-time through SET
commands, while others (language, date/time separators, character
set, and the -u option) must be chosen at compile-time. Pass these
using `VAR=value ./remind.SlackBuild`:
LANGUAGE=LANG (default: ENGLISH), set the language. See the SlackBuild
for possible language options.

LAT_DEG=# (default: 45), set the latitudinal degrees
LAT_MIN=# (default: 24), set the latitudinal minutes
LAT_SEC=# (default: 0), set the latitudinal seconds
LON_DEG=# (default: 75), set the longitudinal degrees
LON_MIN=# (default: 39), set the longitudinal minutes
LON_SEC=# (default: 0), set the longitudinal seconds
LOCATION=location (default: Ottawa), set the location string
See the SlackBuild for more information on these variables.

DEFAULT_PAGE=Letter|A4 (default: Letter), set the default page size
DATESEP=-|/ (default: -), set the date separator character
TIMESEP=:|. (default: :), set the time separator character

CHARSET=ASCII|ISOLATIN1|ISOLATIN2|IBMEXTENDED|IBM852
(default: ISOLATIN1), set the character set to use

WANTU=yes|no (default: yes), enable/disable the -u option (which
runs remind with the uid and gid of the specified name)

There are a number of graphical front-ends to remind. tkremind is
included, but requires tcllib (available from SlackBuilds.org) as
a run-time requirement. Using remind via the command-line (or via
other front-ends) does not require tcllib.
