Automatic Package Installation

PSRCHIVE includes a number of scripts that may be used to automatically install its dependencies. These scripts are created by the configure script, which must be run first. After installing all of the required packages and setting the relevant environment variables as instructed, the configure script must be run again. For example, 
./configure
./packages/fftw.csh
./packages/cfitsio.csh
./packages/pgplot.csh
# set the PGPLOT_DIR and PGPLOT_FONT environment variables
./packages/tempo2.csh
# set the TEMPO2 environment variable
./packages/psrcat.csh
# set the PSRCAT_FILE environment variable
./configure
