-/* Este fichero es http://ecce.sourceforge.net/ecce.c +
-   It is written in reasonably portable C and should +
-   be easy to compile with any C compiler, eg on Linux: +
-   cc -o ecce -DWANT_UTF8 ecce.c +
- +
-   You may need to do: export LC_ALL=en_US.UTF-8 +
- +
-   Although it's reasonable portable C, there are now +
-   a couple of places where linux filenames are used - +
-   you may need to make some small changes if compiling +
-   for Windows or other non-unix systems.  Look for *SYS* +
-   in the source below.  Feedback portability improvements +
-   to gtoal@gtoal.com please.  Note that we assume that +
-   even a linux system is single-user.  The use of +
-   tmpnam() for saving in an emergency is potentially +
-   unsafe in a multi-user environment if there are +
-   bad actors. +
- +
-   Version 2.10a adds support for more robust embedding +
-   of ecce in Emacs, by making a version of the "-command" +
-   parameter (-hex-command) accept a hex string in order +
-   to pass the ecce command as a parameter while avoiding +
-   problems such as the use of " characters in the ecce command. +
