Detailed installations instructions are in the HTML documentation, which
you can find in doc/1.manual.
Quick compilation instructions for Linux or Mac OSX (assuming for Mac OSX that
you've got Tck/Tk installed):
Change to "src" subdirectory.
type "./configure", possibly adding flags as follows:
To put Pd in /usr/bin instead of /usr/local/bin, add "--prefix=/bin".
To enable jack support: "--enable-jack"
Type "make depend" and then "make"; or, if you prefer, as superuser
type "make install".
To run pd, either type the full pathname as in /home/me/pd/bin/pd, or else
if you've chosen "make install", just type "pd".
