Remove All CVS Id Strings Possible Using a Script

Script does what is expected and tries to do it as
smartly as possible.

+ remove occurrences of two blank comment lines

next to each other after Id string line removed.

+ remove entire comment blocks which only exited to

contain CVS Ids

+ If the processing left a blank line at the top of

a file, it was removed.

Line
1	This is a "problem" test in Ada versus the C equivalent. In C,
2	we used macros to :
3
4	+ declare a LOT of local integer and floating point variables
5	+ load them with values
6	+ check them at certain times
7	+ to avoid floating point operations on CPUs w/o hardware support
8
9	The macros are not equivalent to subprograms doing the same thing.
10	We are trying to insure that the register set is fully utilized and
11	checking that it survives context switches. If the routines are
12	subprograms, then calling conventions and scoping rules apply. Thus
13	the variables do not exist throughout the entire life of the task
14	as in the C test.
15
16	It seems to point out that although the conditional compilation
17	and macro capabilities of C are often abused, they do provide
18	capabilities which are difficult if not impossible to mimic entirely
19	with subprograms.
