B.17.5 | Multiple Indexes with the `index` and `multind` package

HEVEA supports several simultaneous indexes, following the scheme of the `index` package, which is present in modern LATEX distributions. This scheme is backward compatible with the standard indexing scheme of LATEX.
Support is not complete, but the most useful commands are available. More precisely, HEVEA knows the following commands:

`\newindex{`tag`}{`ext`}{`ignored`}{`indexname`}`
  Declare an index. The first argument tag is a tag to select this index in other commands; ext is the extension of the index information file generated by LATEX (e.g., `idx`); ignored is ignored by HEVEA; and indexname is the title of the index. If given the `idx` option. HEVEA attempts to read file mydoc`.`ext. There also exists a `\renewindex` commands that takes the same arguments and that can be used to redefine previously declared indexes.
`\makeindex`
  Perform `\newindex{default}{idx}{ind}{Index}`.
`\index[`tag`]{`arg`}`
  Act as the LATEX `\index` command except that the information extracted from arg goes to the tag index. The tag argument defaults to `default`, thereby yielding standard LATEX behavior for the `\index` command without an optional argument. There also exists a stared-variant `\index*` that Additionally typesets arg.
`\printindex[`tag`]`
  Compute, format and output index whose tag is tag. The tag argument defaults to `default`. At the moment, there is an important difference between LATEX and HEVEA: for `\printindex` to work, if must occur after the last occurrence of the `\index` command. This is little problem in practise, since indexes usually reside at the end of books.

The `multind` package provides another scheme for multiple indexes. Note that the ```multind`'' style for indexes is not backward compatible with LATEX default indexing scheme. I would recommend using the ```index`'' package.
