# USE THIS SCRIPT TO REPLACE ALL OCCURENCES OF *.Rout.save WITH NEW *.Rout FILES
#
# Author: Benjamin Hofner, 2012-2014
#
# USAGE:
#   Use either
#     ## To copy test output
#     Rscript copy_Rout_to_Routsave.R "vignettes=FALSE"
#     ## To copy vignette output
#     Rscript copy_Rout_to_Routsave.R "vignettes=TRUE"
#
# ALTERNATIVE USAGE (with R CMD BATCH):
#   Use either
#     ## To copy test output
#     R CMD BATCH "--args vignettes=FALSE" copy_Rout_to_Routsave.R
#     ## To copy vignette output
#     R CMD BATCH "--args vignettes=TRUE" copy_Rout_to_Routsave.R
