Introduction to my PC Parallel Port tools project

Aim was my desire to play around with the parallel port.

Basicall this program can just write, read and read-modify-write the 3
registers on any of the 3 PC parrallel ports. The rest ist various nice to
have comfort features.

Read the man page with  man parport  , or use the on-line help with  parport -h

Note that this program must run SUID root. Read the SECURITY section in the man
page about this.
