# ENV SETTINGS:
# About the locale:  some functions use locale information.  In particular,
# Logwatch makes use of strftime, which makes use of LC_TIME variable.  Other
# functions may also use locale information.
#
# Because the parsing must be in the same locale as the logged information,
# and this appears to be "C", "POSIX", or "en_US", we set LC_ALL for
# this and other scripts invoked by this script.  We use "C" because it
# is always (?) available, whereas POSIX or en_US may not.  They all use
# the same time formats and rely on the ASCII character set.
#
# Variables REAL_LANG and REAL_LC_ALL keep the original values for use by
# scripts that need native language.
