version 0.5.3 (Sat Dec  2)
	fixed incorrect handling with a notation of float numbers (xEy didn't
	correspond to xE+y),

	add to parser a trap for increment and decrement operators.

	bug-fixes in parser, calc3.

version 0.5.2 (Tue Oct  7)
	bug-fix in calc3 parser of command line options,

	added new methods in mssg, documented its methods,

	deleted strError() and getExpr() from forint.

version 0.5.1 (Tue Oct  5)
	rebuild mssg, cmssg classes, calc3,

	new print mode -- typewriter-like one,

	bug-fix in calc3.

version 0.4.4 (Tue Sep  5)
	made russification of messages.

version 0.4.2 (Sun Aug 27)
	added possibility to pass options to compiler for DLF compilation,

	made some optimization of virtual machines.

version 0.4.1 (Thu Aug 24)
	extended parse by new flags: separate flags of accessibility for
	built-in variables and for @t{rl} and @t{self} tokens, flag of zeroing
	of built-in variables,

	by default built-in variables aren't zeroed by the @t{parse()} call,

	new method --- clear(),

	an important bugfix in decompose().

version 0.3.5 (Mon Aug 21)
        some improvement in the `while' statement diagnostics,

        fixed serious bugs in decompose() and VMs -- in some cases (some
        nested statements requiring non-sequential execution) VMs returned
        an invalid result (bugs appeared for the `while' statement adding)


version 0.3.4 (Sun Aug 20)
	some optimization of VMs (lazy && and ||)

	added new testing formula in speedtest.cc,

	bug-fixes:
	  in makeDLF() for complex expressions,
	  in parse() -- added d_b_cast_pos and d_e_cast_pos clearing,

	bug-fixes in DLF generator for `while' statement,

	new environment variable `FORINT_INCL_DIR', meant
	for dlf compilation. If forint has been installed in a non-standard
	directory the variable is used to pass compiler the path to
	`forint/forint.hh' file.

version 0.3.3 (Fri Aug 18)
	added `while' control statement, now real loops may be used in forint,
	getPBrk() method returns a pointer to the `break_flag',
