Capture output from a command-line program

I would like to run a command-line program from a Kylix GUI
application and display the output of the command-line program in a
TMemo in the GUI application. What is the best way to capture the
output from the command-line program?

The Libc.popen() function is the easiest way but has it's limits.

A more complex but also more powerfull method is to fork(), pipe() and
execXx().

See the Execute function in JclSysUtils.pas from the JCL library here:
