a general-purpose xkcd fetching bash script
xkfetch depends on feh, curl, and bc; all of which should be available via your package manager
- use "chmod +x xkfetch" to make xkfetch executable
- throw xkfetch into a folder included in your PATH, like /usr/bin
- 05|11|14 - v0.7: General betterification, including spitting out a link if the fetched xkcd is "special." Added bc as a dependency.
- 03|06|14 - v0.6.1: Small tweaks, including the xkcd's title showing up.
- 03|04|14 - v0.6: Added -m for repeated randomness
