-# NOTES ABOUT THESE AWESOME REGULAR EXPRESSIONS:
-#
-# * We can't assume GNU sed.  Unfortunately, + and * are GNU extensions.  Thus,
-#   we have to use {1,} for + and {0,} for *.
-# * You don't need to add an extra set of escaped quotes around the sed expression
-#   arguments here - sed_in_place_remotely will do that for you.
-# * Only literal quotes need the triple backslashes.  All other special characters
-#   are fine with just a single one.
-# * sed needs a LOT of characters escaped - \, {, }, (, ), and | at least.
