# == Definition: archive::extract

#

# Archive extractor.

#

# Parameters:

#

# - *$target: Destination directory

# - *$src_target: Default value "/usr/src".

# - *$root_dir: Default value "".

# - *$extension: Default value ".tar.gz".

# - *$timeout: Default value 120.

# - *$strip_components: Default value 0.

# - *$user: The user used to do the extraction.

#

# Example usage:

#

#   archive::extract {"apache-tomcat-6.0.26":

#     ensure => present,

#     target => "/opt",

#   }

#

# This means we want to extract the local archive

# (maybe downloaded with archive::download)

# '/usr/src/apache-tomcat-6.0.26.tar.gz' in '/src/apache-tomcat-6.0.26'

#

# Warning:

#

# The parameter *$root_dir* must be used if the root directory of the archive

# is different from the name of the archive *$name*. To extract the name of

# the root directory use the commands "tar tf archive.tar.gz" or

# "unzip -l archive.zip"

#
