+Penihip - a name generator
+
+Generate new words by applying a caesar cipher to existing words.
+
+Description:
+
+New words are needed for software projects, usernames, commercial
+products. Using existing relevant words as a starting point, Penihip
+applies a specified offset number of characters to shift along the
+alphabet, thereby creating new words. The consonants and vowels are
+shifted within their own set. Therefore the generated words are more
+likely able to be spoken. It does not attempt to handle sentence
+structure, grammar, etc. or be a spoken language generator.
+The name "penihip" is the ciphertext achieved by one-right-shift
+using the plaintext word "namegen" (as in "Name Generator").
+
+It is becoming ever harder to find names for products that are
+not already taken. Creating fanciful new names is one possibility.
+
+Status:
+
+There is a Perl script "penihip" as the initial implementation.
+
+Usage:
+
+Gather some words that describe your product. Words with length between
+four to seven characters seem to yield the best results.
+
+Follow the usage instructions to run the tool, e.g.
+ ./penihip -e < test-encipher-input.txt
+
+Search the internet to ensure that the new words are suitable.
+
+Use a bigger offset number of characters to try for other words, or
+apply a reverse cipher.
+
+Further work:
+
+Perhaps better handling of some cases where multiple vowels will
+create strange words.
+
+Improve the initial Perl implemenmtation.
+
+Perhaps other programming language implementations, e.g. Java.
