"sed libraries"

Hi


I was thinking about a kind of sed "libraries" that can help to convert 
from different formats like html to latex or anything else. Usually, 
there are programs for that but when you want to add something special, 
a sheet for main conversation that can be adapted would be very helpful. 
E.g. I want to convert html to latex, and every <font 16pt ...> should 
give me a subsection entry. I cannot use html2latex as this information 
is lost and no subsection is created. Therefore, I have to create my own 
script, what leaves me with having to set up a huge conversion table for 
all special chars, etc.
For that, a sed script listing all these conversions would be of immense 
help.

Let's create a sed library with such scripts (if it does not exist 
already ...)



See example below.
