From the keyboard of soh@andromeda.trl.OZ.AU (kam hung soh):
:I would like to write a regular expression which can look for patterns
:longer than one line.  For example, I want to find the first line of
:each paragraph.  

It occurs to me I didn't answer the example question.  In perl, you
could solve that problem in this way (and many others as well):

    perl -00 -ne 'print /(.*\n)/' some_file

The -00 put us in paragraph mode, and the (.*\n) isolates the first
line of each paragraph for printing.
