# EM::DeferrableChildProcess is a sugaring of a common use-case

|
# involving EM::popen.

# Call the #open method on EM::DeferrableChildProcess, passing
|
||
|
|
# a command-string. #open immediately returns an EM::Deferrable
|
||
|
|
# object. It also schedules the forking of a child process, which
|
||
|
|
# will execute the command passed to #open.
|
||
|
|
# When the forked child terminates, the Deferrable will be signalled
|
||
|
|
# and execute its callbacks, passing the data that the child process
|
||
|
|
# wrote to stdout.
