Can LGPL be used for non-libraries

[Daniel Qarras]

Hi,

this must be silly question but I can't figure it out:

LGPL is used for many programs that certainly are not "software 
libraries". A well-known example could be OpenOffice.org. However, LGPL 
2.1 section 2. says:

"a)  The modified work must itself be a software library."

Surely if I make some minor changes to, e.g., OO.o's Writer it does not 
turn into "a software library". How come that OO.o and other non-library 
programs can use LGPL even if they not "libraries"?
