Finding Badly Referenced Nodes
==============================
You can use the `Info-validate' command to check whether any of the
`Next', `Previous', `Up' or other node pointers fail to point to a
node. This command checks that every node pointer points to an
existing node. The `Info-validate' command works only on Info files,
not on Texinfo files.
The `makeinfo' program validates pointers automatically, so you do
not need to use the `Info-validate' command if you are using
`makeinfo'. You only may need to use `Info-validate' if you are unable
to run `makeinfo' and instead must create an Info file using
`texinfo-format-region' or `texinfo-format-buffer', or if you write an
Info file from scratch.
