+foreman(1) -- manage Procfile-based applications
+================================================
+
+## SYNOPSIS
+
+`foreman start [process]`<br>
+`foreman export <format> [location]`
+
+## DESCRIPTION
+
+**Foreman** is a manager for Procfile-based applications. Its aim is to
+abstract away the details of the Procfile format, and allow you to either run
+your application directly or export it to some other process management
+format.
+
+## RUNNING
+
+`foreman start` is used to run your application directly from the command line.
+
+If no additional parameters are passed, foreman will run one instance of each
+type of process defined in your Procfile.
+
+If a parameter is passed, foreman will run one instance of the specified
+application type.
+
+The following options control how the application is run:
+
+  * `-c`, `--concurrency`:
+    Specify the number of each process type to run. The value passed in
+    should be in the format `process=num,process=num`
+
+  * `-p`, `--port`:
+    Specify which port to use as the base for this application. Should be
+    a multiple of 1000.
+
+## EXPORTING
+
+`foreman export` is used to export your application to another process
+management format.
+
+An location to export can be passed as an argument. This argument may be
+either required or optional depending on the export format.
+
+The following options control how the application is run:
+
+  * `-a`, `--app`:
+    Use this name rather than the application's root directory name as the
+    name of the application when exporting.
+
+  * `-c`, `--concurrency`:
+    Specify the number of each process type to run. The value passed in
+    should be in the format `process=num,process=num`
+
+  * `-l`, `--log`:
+    Specify the directory to place process logs in.
+
+  * `-p`, `--port`:
+    Specify which port to use as the base for this application. Should be
+    a multiple of 1000.
+
+  * `-u`, `--user`:
+    Specify the user the application should be run as. Defaults to the
+    app name
+
+## OPTIONS
+
+These options control all modes of foreman's operation.
+
+  * `-e`, `--env`:
+    Specify an alternate environment file. You can specify more than one
+    file by using: `--env file1,file2`.
+
+  * `-f`, `--procfile`:
+    Specify an alternate location for the application's Procfile. This file's
+    containing directory will be assumed to be the root directory of the
+    application.
+
+## EXPORT FORMATS
+
+foreman currently supports the following output formats:
+
+  * bluepill
+
+  * inittab
+
+  * upstart
+
+## INITTAB EXPORT
+
+Will export a chunk of inittab-compatible configuration:
+
+    # ----- foreman example processes -----
+    EX01:4:respawn:/bin/su - example -c 'PORT=5000 bundle exec thin start >> /var/log/web-1.log 2>&1'
+    EX02:4:respawn:/bin/su - example -c 'PORT=5100 bundle exec rake jobs:work >> /var/log/job-1.log 2>&1'
+    # ----- end foreman example processes -----
+
+## UPSTART EXPORT
+
+Will create a series of upstart scripts in the location you specify. Scripts
+will be structured to make the following commands valid:
+
+  `start appname`
+
+  `stop appname-processname`
+
+  `restart appname-processname-3`
+
+## PROCFILE
+
+A Procfile should contain both a name for the process and the command used
+to run it.
+
+    web: bundle exec thin start
+    job: bundle exec rake jobs:work
+
+You can validate your Procfile format using the `check` command
+
+    $ foreman check
+
+## ENVIRONMENT
+
+If a `.env` file exists in the current directory, the default environment will
+be read from it. This file should contain key/value pairs, separated by `=`, with
+one key/value pair per line.
+
+    FOO=bar
+    BAZ=qux
+
+## DEFAULT OPTIONS
+
+If a `.foreman` file exists in the current directory, default options will
+be read from it. This file should be in YAML format with the long option
+name as keys. Example:
+
+    concurrency: alpha=0,bravo=1
+    port: 15000
+
+## EXAMPLES
+
+Start one instance of each process type, interleave the output on stdout:
+
+    $ foreman start
+
+Export the application in upstart format:
+
+    $ foreman export upstart /etc/init
+
+Run one process type from the application defined in a specific Procfile:
+
+    $ foreman start alpha -p ~/myapp/Procfile
