# NAME:
|
|
# os.sh - operating system specifics
|
|
#
|
|
# DESCRIPTION:
|
|
# This file is included at the start of processing. Its role is
|
|
# to set the variables OS, OSREL, OSMAJOR, MACHINE and MACHINE_ARCH to
|
|
# reflect the current system.
|
|
#
|
|
# It also sets variables such as MAILER, LOCAL_FS, PS_AXC to hide
|
|
# certain aspects of different UNIX flavours.
