The runtest file syntax is simple:

* Start of the line until first whitespace is test id
  the rest of the line is command line to be executed

* Every line starting with # is comment

All test binaries are installed into a single directory. To get the test
source you need to locate the executable name in the command line part
of the corresponding line, then do something as find -name foo* in the
LTP source tree. You will likely end up either with C source or a shell
script.
