Tiny chatbot living in a text file.
PocketBot is a simple self-modifying bash script that uses levenshtein distancing to intelligently respond to queries.
The central database containing its input/output pairs is contained in a variable named brain at line 133 (as of now).
Each element of this variable contains an input/output pair that are separated by a chinese doll emoji. (chosen due to low usage frequency and issues with the current string split bash implementation)
