+Fichero README del programa para encriptar claves de nick para
+introducir en la tabla 'n'.
+
+
+ COMPILACION en LINUX o entornos UNIX
+Para compilarlo necesitas el Make y gcc de gnu, lo podras encontrar
+en http://www.gnu.org. Se compila tecleando "gmake" o "make".
+
+
+ COMPILACION en WINDOWS
+Si tienes el suite Visual Studio o uno de sus partes Visual C++, puedes
+hacerlo en modo grafico o en modo consola.
+En modo consola se hace con "cl cifranick.c ws2_32.lib" y te generará un
+ejecutable *.exe
+
+
+Para utilizar el programa hay que teclear en la consola:
+
+ En Linux/UNIX:
+ ./cifranick <nick> <clave>
+ En Windows:
+ cifranick <nick> <clave>
+
+siendo <nick> el nick del usuario para encriptar su clave y
+<clave> la clave del usuario. (Notese que si la clave mide mas de
+12 caracteres, se trunca a 12 caracteres).
+El programa devolvera el nick normalizado en minusculas teniendo en
+cuenta lo siguiente
+ La minuscula de ^ es ~
+ " " de \ es |
+ " " de [ es {
+ " " de ] es }
+y la clave sale encriptada, lista para meterla en la tabla 'n'.
+
+
+Para dudas, preguntas, sugerencias, puede comentarlas en el canal
+#irc-dev del iRC-Hispano o visitar la web http://www.irc-dev.net y
+exponerlas en los foros.

+PD: La may£scula de NiCK es nick2 ;-)
