I know, it's only AWKward, but I like it...

A nice little Awk program that generates git directories per language based on the contents of two files:

BEGIN {

    file="langs.txt"; 

    while((getline < file ) > 0 ) { 

        langs[$1] = 1  # record each language

    }   

}

/^$/ { }     # blank lines allowed

/^\;/ { }    # allows comments in the chapter file

/^[IVXCM]/ { } # skip the major section names

/^[0-9]/ {

    print $2

    for( lang in langs ) { 

        new_dir = lang "/" $2

        if (system( "[ -d " new_dir " ] ") == 0)

            print new_dir " already exists."

        else {

            print "We are going to add " new_dir

            if (system( "mkdir " new_dir) == 0) {

                system( "touch " new_dir "/README")

                system( "git add " new_dir "/README")    

            }   

        }   

    }   

}
