Configure.pl - $lang Configure
General Options:
--help Show this text
--prefix=dir Install files in dir; also look for executables there
--backends=jvm,moar
Which backend(s) to use (or ALL for all of them)
--gen-nqp[=branch]
Download and build a copy of NQP
--gen-moar[=branch]
Download and build a copy of MoarVM to use
--moar-option='--option=value'
Options to pass to MoarVM's Configure.pl
--git-protocol={ssh,https,git}
Protocol used for cloning git repos
--git-depth=<number>
Use the --git-depth option for git clone with parameter number
--git-reference=<path>
Use --git-reference option to identify local path where git repositories are stored
For example: --git-reference=/home/user/repo/for_perl6
Folders 'nqp' and 'MoarVM' with corresponding git repos should be in for_perl6 folder
--makefile-timing Enable timing of individual makefile commands
Configure.pl also reads options from 'config.default' in the current directory.
