## 1 How to get started

Assume that you have a file, `a.tex`, written in LATEX, using the `article`, `book` or `report` style. Then, translation is achieved by issuing the command:

    # hevea a.tex

Probably, you will get some warnings. If HEVEA does not crash, just ignore them for the moment (Section 4 explains how to correct errors).

If everything goes fine, this will produce a new file, `a.html`, which you can visualize through a HTML browser.

If you wish to experiment HEVEA on small LATEX source fragments, then launch HEVEA without arguments. HEVEA will read its standard input and print the translation on its standard output. For instance:

    # hevea
    $x \in \mathcal{E}$
    ^D
    <I>x</I> &#X2208; <FONT COLOR=red><I>E</I></FONT>

Incidentally, notice that the symbol “∈” translates to the appropriate numerical character reference and that the calligraphic letter “E” renders as a red “E”. You can find some more elaborate examples in the on-line documentation.
