-'''Pseudotranslation support.  Our pseudotranslations are based on the
-P-language, which is a simple vowel-extending language.  Examples of P:
-  - "hello" becomes "hepellopo"
-  - "howdie" becomes "hopowdiepie"
-  - "because" becomes "bepecaupause" (but in our implementation we don't
-    handle the silent e at the end so it actually would return "bepecaupausepe"
-
-The P-language has the excellent quality of increasing the length of text
-by around 30-50% which is great for pseudotranslations, to stress test any
-GUI layouts etc.
-
-To make the pseudotranslations more obviously "not a translation" and to make
-them exercise any code that deals with encodings, we also transform all English
-vowels into equivalent vowels with diacriticals on them (rings, acutes,
-diaresis, and circumflex), and we write the "p" in the P-language as a Hebrew
-character Qof.  It looks sort of like a latin character "p" but it is outside
-the latin-1 character set which will stress character encoding bugs.
