########################################################################
####  CONVENTIONS:
####  Indentation: TABS
####  Do not use `....`, those are totally non-reabable, use $(....)
####  Do not use one liner flow controls. The ONLY time you should use ; is in
####  this single case: if [ condition ];then (ie, never: [ condition ] && statement)
####
####  All new code/methods must be in a function.
####  For all boolean tests, use 'true' / 'false'. Do NOT use 0 or 1 unless
####  it's a function return. Avoid complicated tests in the if condition itself.
####
####  VARIABLE/FUNCTION NAMING:
####  All variables should explain what they are, except counters like i, j
####  All variables MUST be initialized / declared explicitly
####, globals UPPER CASE, at top of script, SOME_VARIABLE='' (words separated by _ ).
####  Locals always: local someVariable= (lower case, all except first word started upper case)
####  and at the top of the function. ie: testTrunkData
####
####  Booleans should start with b_ or B_ and state clearly what is being tested
####	Arrays should start with a_ or A_
####  All functions should follow standard naming, ie, verb adjective noun, get_cpu_data
########################################################################
####  TESTING FLAGS
####  sgfxi supports advanced testing triggers to do various things, using -! <arg>
####  -! 1 - triggers default B_TESTING_1='true' - triggers testing data function
####  -! 2 - triggers default B_TESTING_2='true' - triggers post test exit
####  -! 3 - triggers default B_SKIP_FUNCTION='true' to turn off functions for script testing
####  -! 4 - triggers B_TESTING_1='true' and B_TESTING_2='true'
####  -! 5 - triggers B_TESTING_1='true', B_TESTING_2='true', and B_SKIP_FUNCTION='true'
####  -! 6 - triggers B_TESTING_3='true' - overrides xorg/kernel support tests
####  -! 7 - triggers B_TESTING_4='true' - overrides patch tests
####  -! 8 - triggers B_TESTING_5='true' - triggers advanced, beta tests for general script
####  -! 9 - triggers B_TESTING_6='true' - triggers new distro development tests
####  -! 10 - triggers an update from the primary dev download server
####  -! 11 - triggers an update from svn branch one - if present, of course
####  -! 12 - triggers an update from svn branch two - if present, of course
####  -! <http://......> - Triggers an update from whatever server you list.
####  -! 20 - uses patch from svn branch one server (must be in branch/one/patches)
####  -! 21 - uses patch from svn branch two server (must be in branch/two/patches)
