var gettysburg = "  Four score and seven years ago our fathers brought forth on\n" +
	"this continent, a new nation, conceived in Liberty, and dedicated\n" +
	"to the proposition that all men are created equal.\n" +
	"  Now we are engaged in a great Civil War, testing whether that\n" +
	"nation, or any nation so conceived and so dedicated, can long\n" +
	"endure.\n" +
	"  We are met on a great battle-field of that war.\n" +
	"  We have come to dedicate a portion of that field, as a final\n" +
	"resting place for those who here gave their lives that that\n" +
	"nation might live.  It is altogether fitting and proper that\n" +
	"we should do this.\n" +
	"  But, in a larger sense, we can not dedicate  we can not\n" +
	"consecrate  we can not hallow  this ground.\n" +
	"  The brave men, living and dead, who struggled here, have\n" +
	"consecrated it, far above our poor power to add or detract.\n" +
	"The world will little note, nor long remember what we say here,\n" +
	"but it can never forget what they did here.\n" +
	"  It is for us the living, rather, to be dedicated here to the\n" +
	"unfinished work which they who fought here have thus far so\n" +
	"nobly advanced.  It is rather for us to be here dedicated to\n" +
	"the great task remaining before us  that from these honored\n" +
	"dead we take increased devotion to that cause for which they\n" +
	"gave the last full measure of devotion \n" +
	"  that we here highly resolve that these dead shall not have\n" +
	"died in vain  that this nation, under God, shall have a new\n" +
	"birth of freedom  and that government of the people, by the\n" +
	"people, for the people, shall not perish from this earth.\n" +
