REQUIREMENTS:
	- postgreSQL 8.4.4 installed
	- postgreSQL programs (initdb, psql etc.) in PATH (check with env)
  	- postgres_src_path: path to source code that includes config, contrib, doc, src etcetera
 						
WITH INSTALL SCRIPT:
 0. call install_src.sh:
 	mkdir ~/qImporter
 	unzip qImporter.zip -d ~/qImporter
 	cd ~/qImporter
 	chmod a+x install_src.sh  
 	./install_src.sh postgres_src_path 
 		
 1. start postgres server:
	pg_ctl -D ~/qvestorDB start
	
 2. import tokens (NOTE: SQL SCRIPT MUST BE CHANGED; ABSOLUTE PATH TO TEST FILE MUST BE PROVIDED):
	psql -d qvestor -f ~/qImporter/import_tokens.sql

 3. stop postgreSQL server:
	pg_ctl -D ~/qvestorDB stop

	
MANUALLY:
 0. change Makefile in contrib folder:
 	sed 's/WANTED_DIRS = \\/WANTED_DIRS = \\\n\t\t qImporter\\/' postgres_src_path/contrib/Makefile > postgres_src_path/contrib/Makefile_new
 	cp postgres_src_path/contrib/Makefile_new postgres_src_path/contrib/Makefile
	rm postgres_src_path/contrib/Makefile_new
	
 1. create directory in contrib & unzip src archive:
 	mkdir postgres_src_path/contrib/qImporter
 	unzip qImporter.zip -d postgres_src_path/contrib/qImporter
 	
 2. call make:
 	cd postgres_src_path/contrib/qImporter
 	make
 
 3. initialize the database:
 	initdb -D ~/qvestorDB 
 	
 4. copy shared object to database folder:
 	cp qImporter.so ~/qvestorDB
 	
 5. start postgreSQL server:
 	pg_ctl -D ~/qvestorDB start
 	
 6. create database:
 	createdb -h localhost qvestor
 	
 7. create token table:
 	psql -d qvestor -f ~/qImporter/createTokTab.sql
 	
 8. register function:
 	psql -d qvestor -f ~/qImporter/qImporter.sql
 	
 9. import tokens (NOTE: SQL SCRIPT MUST BE CHANGED; ABSOLUTE PATH TO TEST FILE MUST BE PROVIDED):
	psql -d qvestor -f ~/qImporter/import_tokens.sql

 10. stop postgreSQL server:
	pg_ctl -D ~/qvestorDB stop
