+#
+# 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.
