# SAMPLE NAME: extractFilesForCommittedLevel
#
# FUNCTIONS:   This sample shell script extracts the committed files
#              associated with a specific committed level in a release,
#              and places them in the path specified by 
#              the relativePathName parameter.
#              This is equivalent of doing a delta extract on the committed
#              level.
#
# USAGE:  extractFilesForCommittedLevel releaseName levelName relativePathName
#
# ENVIRONMENT VARIABLE(S): CMVC_FAMILY [CMVC_BECOME]
