# 'make' description file for building PhysioBank search tools
#
# 'make install' compiles and installs the standalone search tool (pbsqs), the
# server (pbsqsd), the plugins (pbs-and, pbs-not, etc.), the help and HTML
# files, and the web and command-line clients (pbsearch and pbsqsc);  it
# then (re)starts the server, and (using pbsqsc) recreates the list of all
# records (RECORDS-ALL).  If you want the server to start automatically
# whenever the computer is rebooted, you must set up this behavior manually
# (typically by adding 'pbsqsd' to '/etc/rc.local').
#
# 'make check' runs a minimal test to verify that the server is running and
# that it returns the expected result when asked for the number of records
# in the MIT-BIH Arrhythmia Database (48, which has not changed since 1979).
#
# By default, the server initializes itself by reading a local copy of
# physiobank-index in /home/physionet/html/physiobank/database (see
# pbsqs.h).  If you remove '-DLOCAL' from the rule for compiling
# daemon.o or standalone.o, however, the server or standalone tool,
# respectively, will read the current copy of physiobank-index from
# physionet.org (see pbsqs.h).  This may affect startup time
# (typically 1 or 2 seconds) if the network connection is slow, but it
# does not affect response time once the initialization is complete,
# since the server keeps the index in memory and does not re-read it unless
# signalled to do so. (Send it a SIGHUP, e.g., by 'killall -HUP pbsqsd',
# to force it to reread the index if it has been updated.)
