DESCRIPTION

         asql provides a simple console interface to allow a user to
        query the contents of an Apache logfile via an SQL interface.

         The shell features include:

       Persistent alias definitions.
       Command line completion
       Command history
       Simple scriptability

INTRODUCTION

         The asql shell will create a temporary SQLite database based upon
        any number of Apache logfiles.  This temporary database may then
        be interactively queried using common SQL syntax.

         To get started you should load your logfiles into the database:

          load /var/log/apache2/acces*

         (The tool will automatically decompress files which have been
        compressed with gzip or bzip2.)

         Once you've loaded at least one file you may run queries, for
        example:

         SELECT source,SUM(size) AS Number FROM logs GROUP BY source ORDER BY Number DESC, ip

         This example shows all the clients connecting to your webserver
        and the size of files/requests that they have downloaded in total.

         As you can see we've selected two columns "source" and "SUM(size)".
        To see which other columns are available you may execute the "show"
        command.

         Because parsing the Apache logfile(s) specified might be quite
        slow there is the option of dumping the temporary SQLite database
        to a known filename with the 'save' command.  The analog to the
        save command is the 'restore' command, which will read in an
        existing SQLite database and allow future queries to be executed
        against it.

FILES

        When the shell starts up it will read and intepret the initialisation
        file of ~/.asqlrc if it exists.  Any commands present in that file
        will be executed prior to the launch of the interactive session.

        All aliases will be read and written to the file ~/.asql.aliases.

        All interactive history will be written to the file ~/.asql.
