Starts a loop block which will loop until loop-condition is no longer satisfied.

This is much like while loops in most standard programming languges. The first condition can be set to (true or false), and the loop-condition uses the conditional operators (<<, >>, ==, !=, <=, >=, , and ) to satisfy the condition.

command is the command that's carried out at the end of the loop. Often times loops include incrementing a variable as the command at the end of the loop. An example loop would be "loop:true;var.i<<30;var:i=var.i+1" which would loop until the variable "i" was over 30.

When inside of a loop, the variable being used can be referenced by using "[]" brackets i.e: "dom.a.[var:i].innerhtml=foo" would set all of the link names in the loop range to "foo".

All loops must include an endloop call afterwards at risk of looping infinitely.
