Making and installing ptags should be straightforward.  Two things need
to be done before attempting to compile and link the program on your
system.

First edit Makefile and set DFLAGS to be either -DBSD4_2 (the default)
or -DSYSV, depending on which system you are using.  If you're not
using either of these you may have to make some changes to the code -
sorry.  You may also want to change the assignments to FINALVN such
that ptags is installed somewhere else.

Second make sure you know which characters your Prolog treats as
symbols.  Edit config.h and make any necessary changes to my
definitions.

After you have gone through these two stages you should be ready to
type 'make ptags' or 'make install'.

Happy tagging!
