+*Fairly Arbitrary Questions*
+
+### Why?
+
+kyaa exists for when the "quick 'n' dirty" isn't dirty enough.
+also, it keeps argument parsing *in* main,
+instead of delegating with callbacks and whatnot.
+
+### How?
+
+kyaa secretly wraps flag-handling in if-else statements with curly braces.
+it's not a switch-case method!
+kyaa instead uses `continue` to handle certain arguments.
+
+### Should I use this?
+
+honestly, no.
+
+### What's in a name?
+
+i have no idea why i called it "kyaa,"
+other than it being the first thing that came to mind
+that wasn't already in use by some other software.
+
+### What do I need?
+
+the prerequisites are:

-standard library headers:
 * `stdbool.h`
-* `stdio.h`
+
+* `stdio.h` (can be avoided by overriding `KYAA_OUT` and `KYAA_ERR`)

 * `string.h`
 
-in addition, `kyaa_extra.h` requires `limits.h`,
+* `limits.h` (just for `kyaa_extra.h`, can be avoided by defining `LONG_MIN`)
-or at least `LONG_MIN` to be defined.
