52    There are two indices into the the_indices array.
53    * read_index is the index that points to the list of index
54      entries that we will find if we ask for the list of entries for
55      this name.
56    * write_index is the index that points to the list of index entries
57      that we will add new entries to.
58 
59    Initially, read_index and write_index are the same, but the
60    @syncodeindex and @synindex commands can change the list we add
61    entries to.
62 
63    For example, after the commands
64      @cindex foo
65      @defindex ii
66      @synindex cp ii
67      @cindex bar
68 
69    the cp index will contain the entry `foo', and the new ii
70    index will contain the entry `bar'.  This is consistent with the
71    way texinfo.tex handles the same situation.
72 
73    In addition, for each index, it is remembered whether that index is
74    a code index or not.  Code indices have @code{} inserted around the
75    first word when they are printed with printindex. */
