+# Pre commit hook to run phpcs and abort commits on failures or warnings
+#
+# To use, copy or link to the .git/hooks folder of your repository.
+#
+# This simple script:
+# 1. Determins the width of the current console, so the report is full-width
+# 2. Determins which commit to diff against (to know what is being commited) - 
+#    using a fictional commit if it's the first commit.
+# 3. Skip files which don't exist or are not php files
+# 4. If the commit is multiple files run in summary mode, otherwise show details
+#
+# If phpcs returns a none-zero value (which means errors or warnings where found)
+# The commit will be aborted. A developer can override this pre-commit hook and
+# thus still commit despite the errors or warnings raised with the command:
+#
+# 		git commit --no-verify <same args as before>
