Users wanting to build simulators with locally build dependent packages or
packages provided by an unsupported package management system can
override where this procedure looks for include files and/or libraries.
Overrides can be specified by define exported environment variables or
GNU make command line arguments which specify INCLUDES and/or LIBRARIES.
Each of these, if specified, must be the complete list include directories
or library directories that should be used with each element separated by
colons. (i.e. INCLUDES=/usr/include/:/usr/local/include/:...)
Binaries built with unsupported library components will have a 'unsupported' tag
in the output of the SHOW VERSION command.
Added -Q switch to suppress version check messages
Added -D switch to disable the detach_all at the beginning of a restore and any actual attach operations during the restore
1) Single Command Mode: commands are processed between simulated instructions once CR is received.
2) Multiple Command Mode: commands are initiated with the WRU character (usually *E) which suspends simulation execution and commands are processed until a CONTINUE command is entered (or automatically provided if the SET REMOTE TIMEOUT=seconds interval has elapsed).
