Explanation of the optional installation step 1:
------------------------------------------------

If your local character set is not ISO Latin-1 or if your C compiler is not
8-bit clean, you will have to convert the sources.

Included here is a program for conversion to plain ASCII. Compile it:

    cc cv-to-ascii.c -o cv-to-ascii

Install it somewhere in your path:

    cp cv-to-ascii to-ascii all-to-ascii /usr/local/bin

Convert the sources:

    cd ..
    all-to-ascii src/* utils/* doc/*
