  This example demonstrates how to simply set up a database for export in a
  read-only manner.
  
  Execute with -h or --help to see the available command-line options.
  
  Setup
  -----
  
  The country table (country.sql) can be used for sample data in the database
  of your choice.
  
  Set up the connection in code (method SetUpConnection), 
  or in a connection.ini file with the following format:
  
  [database]
  Type=postgresql
  DatabaseName=YourDatabase
  Host=localhost
  username=me
  password=secret
  port=nnnn
  
  You can use another name as connection.ini, but then you must specify the
  name with the -c or --config option.
  
  Once started, the server will display connection info and available resources.
  
  
  Things to try
  -------------
  The following list possible queries, using either wget or curl:
  (obviously, you can do the same in a browser)
  
  Get a list of available resources:
  wget -q -O - "http://localhost:3000/metadata/"
  curl -o - "http://localhost:3000/metadata/"
  
  Same, but only the names, in compact format:
  wget -q -O - "http://localhost:3000/metadata/?fl=name&fmt=csv&metadata=0"
  curl -o - "http://localhost:3000/metadata/?fl=name&fmt=csv&metadata=0"
  
  
  Get metadata for country table:
  
  wget -q -O - "http://localhost:3000/metadata/country"
  curl -o - "http://localhost:3000/metadata/country"
  
  Only get fieldnames:
  wget -q -O - "http://localhost:3000/metadata/country?fl=name&fmt=csv"
  curl -o - "http://localhost:3000/metadata/country?fl=name&fmt=csv"
  
  Get a list of all countries:
  
  wget -q -O - http://localhost:3000/country
  curl -o - http://localhost:3000/country
  
  Get a list of all countries in compact format:
  wget -q -O - "http://localhost:3000/country?humanreadable=0"
  curl -o - "http://localhost:3000/country?humanreadable=0"
  
  Same as previous, and skip metadata as well:
  wget -O - "http://localhost:3000/country?humanreadable=0&metadata=0"
  curl -o - "http://localhost:3000/country?humanreadable=0&metadata=0"
  
  Get a list of countries in XML format:
  wget -q -O - "http://localhost:3000/country?fmt=xml"
  curl -o - "http://localhost:3000/country?fmt=xml"
  
  Limit returned fields. Get a list of all ISO country codes:
  
  wget -q -O - "http://localhost:3000/country?fl=iso"
  curl -o - "http://localhost:3000/country?fl=iso";
  
  Same, but in CSV format:
  wget -q -O - "http://localhost:3000/country?fl=iso&fmt=csv"
  curl -o - "http://localhost:3000/country?fl=iso&fmt=csv"
  
  Filtering: only ISO3 codes that start with M:
  wget -q -O -  "http://localhost:3000/country?iso3_gte=M&iso3_lt=N"
  curl -o - "http://localhost:3000/country?iso3_gte=M&iso3_lt=N"
  
  Paging: First page, 10 records:
  
  wget -q -O - "http://localhost:3000/country?limit=10"
  curl -o - "http://localhost:3000/country?limit=10"
  
  Paging: Second page, 10 records:
  wget -q -O - "http://localhost:3000/country?limit=10&offset=10"
  curl -o - "http://localhost:3000/country?limit=10offset=10"
