+#  Adapted from https://croc.schollz.com
+#
+#                  croc Installer Script
+#
+#   Homepage: https://schollz.com/software/croc
+#   Issues:   https://github.com/schollz/croc/issues
+#   Requires: bash, mv, rm, tr, type, curl/wget, base64, sudo (if not root)
+#             tar (or unzip on OSX and Windows), gpg (optional verification)
+#
+# This script safely installs croc into your PATH (which may require
+# password authorization).
+#
+# In automated environments, you may want to run as root.
+# If using curl, we recommend using the -fsSL flags.
+#
+# This should work on Mac, Linux, and BSD systems, and
+# hopefully Windows with Cygwin. Please open an issue if
+# you notice any bugs.
