If you have a sed script that is executable as in the first line
starts with
#! /usr/bin/sed -f
and the following lines are like:

/this repetitive line/d
/and another repetitive line to go/d

This all works great. You just make the file executable and use
it as a filter if you want to remove any instance of those lines
in text.

	How does one embed a command in this filter to make sed
understand an extended or modern regular expression like:

/part 1[[:space:]]text\/html[[:space:]]/d

This is normally the -e flag but I haven't figured out how to
put it in the script. I would like to either use it to make that
one line show up as an extended regular expression or make sed
run the entire script in the -e mode.

	In this particular case, I have made a 14-line script
called nuisancefilter that vaporizes annoying blocks of text
from  Email messages.

	I have read the man page and it says that this is
possible, but I never quite understood how to apply the commands
to an executable sed script file.  Many thanks.
