# This script clones the git repositories stored in the $repos list in the
# current directory. Afterwards it looks to see if there's a CMakeLists.txt file
# in the top level project directory and if so it creates build/ and attempts to
# build the project automatically. If it successfully builds then it links the
# executable in the directory the script is located in. After everything is
# complete then it prints out info such as how many repos there are and how many
# built.
