+# foreground-child
+
+[![Build Status](https://travis-ci.org/tapjs/foreground-child.svg)](https://travis-ci.org/tapjs/foreground-child) [![Build status](https://ci.appveyor.com/api/projects/status/kq9ylvx9fyr9khx0?svg=true)](https://ci.appveyor.com/project/isaacs/foreground-child)
+
+Run a child as if it's the foreground process.  Give it stdio.  Exit
+when it exits.
+
+Mostly this module is here to support some use cases around wrapping
+child processes for test coverage and such.
+
+## USAGE
+
+```js
+var foreground = require('foreground-child')
+
+// cats out this file
+var child = foreground('cat', [__filename])
+
+// At this point, it's best to just do nothing else.
+// return or whatever.
+// If the child gets a signal, or just exits, then this
+// parent process will exit in the same way.
+```
+
+A callback can optionally be provided, if you want to perform an action
+before your foreground-child exits:
+
+```js
+var child = foreground('cat', [__filename], function (done) {
+  // perform an action.
+  return done()
+})
+```
+
+## Caveats
+
+The "normal" standard IO file descriptors (0, 1, and 2 for stdin,
+stdout, and stderr respectively) are shared with the child process.
+Additionally, if there is an IPC channel set up in the parent, then
+messages are proxied to the child on file descriptor 3.
+
+However, in Node, it's possible to also map arbitrary file descriptors
+into a child process.  In these cases, foreground-child will not map
+the file descriptors into the child.  If file descriptors 0, 1, or 2
+are used for the IPC channel, then strange behavior may happen (like
+printing IPC messages to stderr, for example).
+
+Note that a SIGKILL will always kill the parent process, _and never
+the child process_, because SIGKILL cannot be caught or proxied.  The
+only way to do this would be if Node provided a way to truly exec a
+process as the new foreground program in the same process space,
+without forking a separate child process.
