# rtrtfilter - "| rtrfilter -x <perl regex> -i <perl regex> -f <regex file> \
# -u <From address> -s <subject> <rcpts>"
# expects to read an email message on stdin containing a diff from
# rancid and emails a filtered copy to <rcpts> with the subject of the
# original msg or the contents of -s <subject>. the perl regex(es) specified
# via -x or -i (exclusive and inclusive, respectively) are applied to the
# router names (ie: files) from the "Index:" of the diff o/p. alternatively,
# the regex's may be specified in -f <regex file> in the form:
# # comment
# x <regex>
# # comment
# i <regex>
# do not include /'s in the regex's.
# eg:
# #i inc1
# i a0[12]\.
# i a0[34]\.
# # comment
# x router\.db
# x ^r0[0-9]
# #i foo
#
# exclusion takes precedence and defaults to nothing. inclusion defaults to
# everything.
