I need very often to modify filenames or replace/delete their parts across huge number of files. I was using sed command for these purposes but recently I have found out that all these tasks can be easily done directly in bash (or zsh) because both of them support so called string manipulation operations.

| // The goals of this function are twofold: | |
| // | |
| // * Provide a way to generate a string guaranteed to be unique when compared | |
| // to other strings generated by this function. | |
| // * Make the string complex enough that it is highly unlikely to be | |
| // accidentally duplicated by hand (this is key if you're using `ID` |

I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.
I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.
This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.

GitHub supports several lightweight markup languages for documentation; the most popular ones (generally, not just at GitHub) are Markdown and reStructuredText. Markdown is sometimes considered easier to use, and is often preferred when the purpose is simply to generate HTML. On the other hand, reStructuredText is more extensible and powerful, with native support (not just embedded HTML) for tables, as well as things like automatic generation of tables of contents.
