On unix systems you should be able to type "make atp" (non-Unix
systems have makefiles located in the "etc" subdirectory).  The
Makefile works with GNU make, DMAKE, and SVR4 make. If you have
problems, inspect system.h and system.c. And be sure to read the
PORTING document in the "docs" subdirectory. If you are not using GCC,
you may have to change the -O2 flags in the makefiles to -O . The
editline subdirectory contains a makefile for the editline library,
which will be invoked by the main makefile. After building ATP,
install it manually:

Four steps to install ATP:

1) put the atp binary in /usr/local/bin or any convenient place in
   your path.

2) chose a directory where you would like the ATP configuration files
   to reside. A subdirectory off your home directory is a good place.

3) place the atprc, and taglines.atp in the directory you chose in 
   step (2), these files are located in the "docs" subdirectory.

4) edit your shell .profile or shell startup rc to set the environment
   variable ATP to point to the directory which you chose in step (2), 
   then edit your atprc to customize your atp settings.
