-# SYNOPSIS

 relx [*options*] [*release-specification-file*]
 
-# DESCRIPTION
+Description
+-----------
 
 Relx assembles releases for an Erlang/OTP release. Given a release
 specification and a list of directories in which to search for OTP
 applications it will generate a release output. That output depends
 heavily on what plugins available and what options are defined, but
-usually it is simple a well configured release directory.

-    relx -c relx.config -l ~/my-dirs  --relname foo --relvsn 0.0.1 --target-spec myapp --target-spec getopt>=0.5.1 -o output-dir
+usually it is simply a well configured release directory.
 
 The *release-specification-file* is optional but otherwise contains
 additional specification information for releases.
