 This repository is an eclectic collection of scripts that typically populate  
 my ~/bin. Most are written in Perl, but there are some Shell and Vim scripts  
 in the mix as well (I try to make a point to include file extensions for  
 those who care what they are).  
 
-* **apin.pl** - avoids pitfalls in running aptitude through **su -c**.

+* **nvidia-installer.pl** offers choice of available versions and automates  
 installation of **nvidia** Xorg drivers from the Debian repos; also offers  
 choice of available Nvidia binary installers and can store default args.
 
+* **pct-err.pl** calculates percent error.
 
+* **perlcalc.pl** acts as a command-line calculator; uses **eval**, and
+only includes a really basic safety net.
+
+* **rmrf.pl** is another example of obfuscated Perl. It probably doesn't  
+work; I haven't tried it.  
+
+* **rua.pl** see **apin.pl**.  
+
+* **std-dev.pl** calculates standard deviation from user input.  
+
+* **systats.pl** provides easy access to system information like active  
+memory, battery charge, CPU temperature, etc.  
+
+* **thunar-edit.pl** is useful as a custom action in Thunar for opening  
+different types of files in their respective editors based on file  
+extensions.  
+
+* **tidy-diff.vim** is a simple Vim script that runs **perltidy** on the  
+current file, splits the current window in diff mode, and highlights the  
+differences between your file and perltidy's output. Run :diffoff to exit  
+diff mode.
+
+* **tint2theme.pl** is a theme switcher for **tint2**; assumes you have all  
+theme files is one directory ( easily configurable ).  
+
+* **urxvt-icon-updater.sh** is a shell script that replaces URxvt's joke of  
+an icon with a more recognizable terminal icon from the Oxygen theme ( you  
+could easily modify this to Gnome/Tango or something else ); requires  
+**convert** from **imagemagick**.
+
+* **wifi-switch.pl** allows you to switch easily between two frequently used  
+wireless networks if you configure your connection through **interfaces(5)**.
+
+* **xdeftheme.pl** swaps pre-defined Xdefaults themes.
