+The long name of the project is crosstool-NG:
+  * no leading uppercase (except as first word in a sentence)
+  * crosstool and NG separated with a hyphen (dash)
+  * NG in uppercase
+
+Crosstool-NG can also be referred to by its short name CT-NG:
+  * all in uppercase
+  * CT and NG separated with a hyphen (dash)
+
+The long name is preferred over the short name, except in mail subjects, where
+the short name is a better fit.
+
+When referring to a specific version of crosstool-NG, append the version number
+either as:
+  * crosstool-NG X.Y.Z
+    - the long name, a space, and the version string
+  * crosstool-ng-X.Y.Z
+    - the long name in lowercase, a hyphen (dash), and the version string
+    - this is used to name the release tarballs
+  * crosstool-ng-X.Y.Z+hg_id
+    - the long name in lowercase, a hyphen, the version string, and the Hg id
+      (as returned by: ct-ng version)
+    - this is used to differentiate between releases and snapshots
+
+The frontend to crosstool-NG is the command ct-ng:
+  * all in lowercase
+  * ct and ng separated by a hyphen (dash)
