# and second piece is used to do the final steps in the install
# If KLIBC_INSTALL is defined it tells us we are descending and we
# use first piece of the file.

# This indicates the location of the final version of the shared library.
# THIS MUST BE AN ABSOLUTE PATH WITH NO FINAL SLASH.

# 1) Create directories, install headers and man pages
