====== click-flatten ======

removes compound elements from a Click configuration

===== SYNOPSIS =====

**click-flatten** 
[//options//]
[//param//=//value// ...]
[//router-file//]

===== DESCRIPTION =====

The
**click-flatten** 
tool flattens a Click router configuration, compiling all its compound
elements away, and writes the resulting configuration to the standard
output. It can also output information about the file.

===== OPTIONS =====

If any filename argument is a single dash "-",
**click-flatten** 
will use the standard input or output instead, as appropriate.

 ? **-c**, **--classes**
 ! Output an alphabetical list of the element classes used by the flattened router file, one per line, instead of the usual configuration.
 ? **-n**, **--elements**
 ! Output an alphabetical list of the element names in the flattened router file, one per line, instead of the usual configuration.
 ? **-d**, **--declaration**
 ! Output the element declarations in the flattened router file, one per line, instead of the usual configuration.
 ? **-f**, **--file** //file//
 ! Read the router configuration to flatten from //file//. The default is the standard input.
 ? **-e**, **--expression** //expr//
 ! Use //expr//, a string in the Click language, as the router configuration to flatten.
 ? **--config**
 ! Output flattened configuration only -- if the input was an archive, ignore other archive elements.
 ? **--expand-vars**
 ! Expand global variables.  By default, **click-flatten**  does not expand global variables into configuration strings, allowing later operations, such as **click-install**, to override their values.
 ? **-o**, **--output** //file//
 ! Write the flattened router configuration to //file//. The default is the standard output.
 ? **--help**
 ! Print usage information and exit.
 ? **--version**
 ! Print the version number and some quickie warranty information and exit.
