# SAMPLE NAME: extractAllFilesForComponent
#
# FUNCTIONS:   This sample shell script extracts all the files 
#              associated with a specific component and places them in 
#              the path specified by the relativePathName parameter.
#              If a file belongs to several releases, one version is
#              extracted for each release, under a subdirectory that is
#              named after the release.
#              The versions of the files can be current (default) or committed.
#
# USAGE: 
# extractAllFilesForComponent componentName relativePathName [current|committed]
#                                                             *******
