---> Commands

* include [filename]
	Executes the file 'filename' and continues execution of the current
	file.
	(Very usefull to keep settings of a bunch of sqlmeta-files in one
	file.)

* print [text]
	Print the text [text].

* host [hostname]
	Set the hostname of the mysql server we will fire our queries at.

* user [username] [password]

	server.

* db [database]
	Select a database on the mysql server.

* info
	Spit out version info etc...

* set [varname] {value}
	Set/unset variables.
	If a value is specified, it is stored as variable [varname].
	Variables can be used anywhere with string ${varname}.
	If set is used without a value, the variable will be unset.

* table [sql query]
	Create a table out of a sql query.
	It's just a 'standard' table, no fancy colors or blinking thingies.
	If you want it any other way, do it yourself with the 'with'
	directive.

* query [sql query]
	Query the mysql server.
	Just dump any results the server returns.
	Could be used to insert something into a table or whatever else
	that doesn't need results.
	If you want results, use the 'table' or 'with' directive instead.

* with [sql query]
   ...
  loop
	Query the mysql server.
	For every line of results the server returns the code between 'with'
	and 'loop' will be executed.
	The result-columns can be used as ${col1}, ${col2}, etc...

* for [variable] in "txt1 txt2 txt3 etc foo bar..."
   ...
  next
	Executes all code between 'for' and 'next' with the variable
	[variable] set to 'txt1', then to 'txt2' etc...



---> Special things you can use in your code

* ${environmentvarname}
	Will be replaced by variable 'environmentvarname'

* ${col1}
	Will be replaced by the first column of the current query.
	(Works only inside a 'with' loop.)
	'1' can be replaced by any column number you like.

* ${form_fieldname}
	If we have POST data from a html <form>, you can use
	${form_whatever} to retrieve the value of input-field 'whatever'.

* \n
	\n in a line will be replaced by a newline character.

	loop>

<sql with "SELECT Name FROM People">
<sql print "${col1}\n">
<sql loop>

<sql for i in "foo bar txt1 txt2";print ${i}>
<sql next>

Something to be looking forward to:

if [string1] == [string2]
