# CHANGES
#
# 20051211: Move most of the logic to check for bad links into get_libnames()
# seds, so we don't wrongly sed out whole link lines. Seems to catch more
# problems, such as ' or ` or -- in a link.
# 20051210: Prefer qfile from portage-utils over equery if it's available.
# Check for ... in "link" lines because configure checks are not links.
# Change get_link_generic() to handle whole lines at a time instead of single
# words, so get_linklines() works.
# 20051210: Rework get_libnames() to use a new style of grep, because the old
# way was broken on some packages from the \b. Also optimize the "Looking for
# libraries" section to only grep the log file once for links and cache it;
# also only grep the link lines ones for a given library, then parse the
# output for static or shared. Should speed things up considerably for large
# packages. I get 5 seconds in Analyzing log and 15 in Looking for libs on an
# xorg-x11-6.8.99.15 log on second run.
# Create get_link_generic() that both sections call with different options.
