# From: asherman@fmrco.com (Aaron Sherman)
#
# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
# This legacy library is deprecated and will be removed in a future
# release of perl.
#
# In particular, this should not be used as an example of modern Perl
# programming techniques.
#
# Suggested alternative: Sys::Hostname

warn( "The 'hostname.pl' legacy library is deprecated and will be"
      . " removed in the next major release of perl. Please use the"
      . " Sys::Hostname module instead." );
