	* this class. Note that the removal of this class was done because it was

	*
	* If you want to be sure that curlpp is cleaned up after you reached 
	* the end of scope of a specific function using curlpp, instantiate 
	* this class. This function call curlpp::initialize() in his

	* decided to use it.

	/**
	* This function returns the number of  seconds  since  January 1st  1970,
	* for the date and time that the datestring parameter specifies. The now
	* parameter is there and should hold the current time to allow the
	* datestring to specify relative dates/times. Read further in the date
	* string parser section below.
	*
	* PARSING DATES AND TIMES
	* A  "date" is a string, possibly empty, containing many items separated
	* by whitespace.  The whitespace may be omitted when no ambiguity
	* arises.  The empty string means the beginning of today (i.e., midnight).
	* Order of the items is immaterial. A date string may contain many
	* flavors of items:
	*
	* calendar date items
	* This can be specified in a number of different ways. Including
	* 1970-09-17, 70-9-17, 70-09-17, 9/17/72, 24 September 1972, 24 Sept 72,
	* 24 Sep 72, Sep 24, 1972, 24-sep-72, 24sep72.  The year can also  be
	* omitted, for example: 9/17 or "sep 17".
	* 
	* time of the day items
	* This  string specifies the time on a given day. Syntax supported
	* includes: 18:19:0, 18:19, 6:19pm, 18:19-0500 (for specifying the time
	* zone as well).
	*
	* time zone items
	* Specifies international time zone. There are a few acronyms
	* supported, but in general you should instead use the specific
	* realtive time compared to UTC. Supported formats include: -1200, MST,
	* +0100.
	*
	* day of the week items
	* Specifies a day of the week. If this is mentioned alone it means that
	* day of the week in the future. Days of the week may be spelled out in
	* full: `Sunday', `Monday', etc or they may be abbreviated to their
	* first three letters, optionally followed by a period. The special
	* abbreviations `Tues' for `Tuesday', `Wednes' for `Wednesday' and `Thur'
	* or `Thurs' for `Thursday' are also allowed. A number may precede a day
	* of the week item to move forward supplementary weeks. It is best
	* used in expression like `third monday'. In this context, `last DAY'
	* or `next DAY' is also acceptable; they move one week before or after
	* the day that DAY by itself would represent.
	*
	* relative items
	* A relative item adjusts a date (or the current date if none) forward
	* or backward. Example syntax includes: "1 year", "1 year ago",
	* "2 days", "4 weeks". The string `tomorrow' is worth one day in the
	* future (equivalent to `day'), the string `yesterday' is worth one
	* day in the past (equivalent to `day ago').
	*
	* pure numbers
	* If the decimal number is of the form YYYYMMDD and no other calendar date
	* item appears before it in the date string, then YYYY is read as
	* the year, MM as the month number and DD as the day of the month, for the
	* specified calendar date.
