Aspect operations tools

use CXC::Envs::Flight;
local %ENV = CXC::Envs::Flight::env(’ska’,’tst’); # Adds Ska and TST env to existing ENV

This module sets environment variables for "Flight" software, which
currently includes aspect operations tools (Ska) and TST tools (TST).
If the "ska" environoment is requested, the following environment vari-
ables are set unless already defined:
Default
SKA /proj/sot/ska
SKA_LIB $SKA/lib
SKA_BIN $SKA/bin
SKA_DATA $SKA/data
SKA_SHARE $SKA/share
SKA_PERLLIB $SKA/lib/perl
MST_ROOT /proj/axaf
MST_PERLLIB ${MST_ROOT}/simul/lib/perl
It also puts SKA_BIN at the head of the PATH and puts SKA_PERLLIB and
MST_PERLLIB at the head of the PERL5LIB path.
If the file .ska_envs is present in the run directory,
CXC::Envs::Flight will use these values to override any defaults or
environment variables. This file consists of name-value pairs, one on
each line:
<VAR> = <VALUE>
Spaces are not important, and lines preceded by # are ignored. Vari-
able substitution (e.g. SKA_LIB = $SKA/my_lib) is not allowed.
Likewise, the TST environment sets all the corresponding variables with
SKA => TST, where the default TST root directory is
Default
TST /proj/sot/tst

The following functions are provided
env(<Flt_env>, ...)
Generates the environment variables for the specified flight
environments. Allowed values of <Flt_env> are ’ska’ and ’tst’.
If multiple values are specified, they are added from left to
right, so libraries/paths from the last one will take prece-
dence.
shell_cmds(<shell_type>, <Flt_env>, ...)
Generates the shell commands to set environment variables for
the specified flight environments. The supported shells are
sh, ksh, csh, and tcsh. Allowed values of <Flt_env> are ’ska’
and ’tst’. If multiple values are specified, they are added
from left to right, so libraries/paths from the last one will
take precedence.
