#  On masking of and by other functions in package "SweaveListingUtils"       
######################################################################

Attention:

*** intentional masking: ***

To be able to use the usual calls to 'library' resp. 'require'
but at the same time register the new symbols for "nice" printing
with TeX package 'listings' with the possibility to "tune" the
corresponding keywordstyle for both the package required/"library"-ed
and respective intermediate packages loaded/attached automatically,
we intentionally base functions 'library' and 'require' --- however 
all these functions may still be used in exactly the same way as 
before masking.

*** non-intentional masking: ***

... nothing discovered so far ...
