# feersum(1p)

feersum app loader

## NAME

feersum - feersum app loader

## SYNOPSIS

```
  feersum [plackup opts] [--pre-fork=N] [app.psgi]
  feersum --native [--listen host:port] [--pre-fork=N] [app.feersum]
```

## DESCRIPTION

Loads the specified app file into a Feersum server.

In both cases, if `"--pre-fork=N"` is specified, that many worker processes are used to serve requests. See Feersum::Runner for details.

If in native mode (when running `"feersum --native"`), currently only a `"--listen"` parameter is accepted.  By default, the server will listen on localhost port 5000.

When running in PSGI mode (non-native), Plack::Runner is used.  See that module for documentation and defaults.
