Modified the directory structure. Added makefile, install and uninstall scripts. Removed some files that need to be refactored.

+#Commands For Dergs
+
+These POSIX shell scripts are meant to be UNIXy - they do one thing each and do it well, so you can sling them together and perform complex tasks.
+Need to check if something is a number? isnum.
+Need to take the last argument and pipe it, executing the rest as a command? lastpipe. (I'll be making one that can offset the location by n later.)
+Need the former, but for the first argument? firstpipe.
+You get the idea!
+
+## What do I need?
+There will be descriptions of these functions embedded on their head, including a requirements list for the applications they call.
+Later, I'll make a script that can tell if one of these is missing and let you know.
+I'd also like to do a --reqs argument that will print these along with an indicator of installation status and a return code.
+
+---
+
+### Why POSIX?
+
+My other project isn't ready yet, and it's good to make POSIX environments friendlier.
+The only problem occurs when an external program is not there.
