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.

37To on the simulator included in lm32-gdb use these commands:
38
39tar sim --hw-device lm32cpu \
40  --hw-device "lm32uart/reg 0x80006000 0x100" \
41  --hw-device "/lm32uart > int int0 /lm32cpu" \
42  --hw-device "lm32timer/reg 0x80002000 0x80" \
43  --hw-device "/lm32timer > int int1 /lm32cpu" \
44  --memory-region 0x08000000,0x4000000
45load

47The simulator is VERY VERY slow when RTEMS is idle.
48To speed this up, add SIMULATOR_FAST_IDLE=1 to the
49configure command.
