- fix scratch shortcut transformation to build target and binary
- scan scratch files for a main function to use them as the target name
- fix CMake generator parsing
- update the -- separator message
- use -- separator to forward CMake flags from ns3
- add --vis option to ns3
- embedded version fixes
Fix NS3_VERSION_PATCH and NS3_VERSION_RELEASE_CANDIDATE default values.
Add check-version target to CMake.
Add --enable-build-version to ns3.
Add --check-profile and --check-version options to ns3.
- process each scratch subdirectory as a single target
- forward ns3 arguments after -- separator to the program to run
- fix escape sequence in command-template help string
- handle modules with very long names
