implementation, except for some built on the c library which dependent on Chez Scheme's FFI.` \n\n\nRunning project: \n\n```\n$ raven run example.sc\n```\n\nif you will run a project compiled:\n\n```\n$ export CHEZSCHEMELIBDIRS=.:lib:/usr/local/lib \n$ export CHEZSCHEMELIBEXTS=.chezscheme.sls::.chezscheme.so:.ss::.so:.sls::.so:.scm::.so:.sch::.so:.sc::.so\n$ scheme exemple.so\n```\n\n\n\nThe project Raven is supported by [theschemer.org](http://theschemer.org)\n\nThe principal developers are: [guenchi](https://github.com/guenchi), [chclock](https://github.com/chclock)\n\nNota Bene: We recommend that the libraries for Raven files use .sc for distinguishing the libraries of r5rs / r7rs small.\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fguenchi%2FRaven","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fguenchi%2FRaven","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fguenchi%2FRaven/lists"}
