# The functions below use parallelized versions of gzip, xz, and bzip2 to
# improve compression/decompression performance of RDS serialization in R.
# Each function searches for the appropriate program (based on the required
# compression format) and if found, offloads the compression handling to the
# external program and therefore leaves R free to do the data import/export.
# The two main functions (saveRDS and readRDS) mask R's native read and write
# functions. The functions have been only tested on macOS, but they must work
# on any Linux/Unix.
#
# Requires the following packages: pxz, pbzip2, and pigz.
