Unpack the distribution file:
gzip -d AVP1.3.tar.gz
tar xvf AVP1.3.tar
If you are using GNU tar, you can combine these two steps:
tar zxvf AVP1.3.tar.gz
This will create a directory, AVP1.3
Now enter the src sub-directory and type make to build the software:
cd AVP1.3/src
make
Finally copy the executable to somewhere appropriate:
cp avp /usr/local/bin
To get help on using AVP, type
avp -h
or even better, read the documentation:
acroread AVP1.3/doc/avp.pdf
