+# This tool will hack the doxygen generated documentation to fix link
+# errors produced by doxygen.
+#
+# This works because most anchors doxygen generates are unique 32 char
+# hash values. To speed up the operation, the tool will not check all
+# the files itself but will let 'linklint' do the grunt
+# work. fix-links.py reads the 'errorX.txt' and 'errorAX.txt' files
+# generated by linklint. These files list links to missing files
+# (errorX.html) and links to missing anchors
+# (errorAX.html). fix-links.py works in the following way:
+#
+# - Build a complete index of all unique anchors found in any html
+#   file. The index will only include *unique* anchors. Anchors found
+#   multiple times are removed from the index
+#
+# - The index is extended to include all unique names of html files
+#
+# - Scn the linklint result and check the bad links against the
+#   index. If the file or anchor is found in the index, an accoringly
+#   corrected link is generated otherwise the link is removed.
+#
+# One additional twak is, that fix-links.py will successively remove
+# initial 'g' charachters from anchors until the link is found in the
+# index. Doxygen seems to create links with the wrong number of 'g'
+# charachters in front sometimes.
