to put an endmarker= ?

For example, if I want to load text from a large! file that looks like this

header line 
header line
1 2.0 3.0
2 4.5 5.7
...
500 4.3 5.4
END
more headers
more headers
1 2.0 3.0 3.14 1.1414
2 4.5 5.7 1.14 3.1459
...
500 4.3 5.4 0.000 0.001
END

Then I can use skiprows=2, but loadtxt will choke when it gets to 'END'.  To
