+# Script to check include/test code for common pybind11 code style errors.
+#
+# This script currently checks for
+#
+# 1. use of tabs instead of spaces
+# 2. MSDOS-style CRLF endings
+# 3. trailing spaces
+# 4. missing space between keyword and parenthesis, e.g.: for(, if(, while(
+# 5. Missing space between right parenthesis and brace, e.g. 'for (...){'
+# 6. opening brace on its own line. It should always be on the same line as the
+#    if/while/for/do statement.
+#
+# Invoke as: tools/check-style.sh
