-TODO:  My formatting function needs to be generalized.  Essentially, I'm
-creating a conky-specific printf function. Right now, it's split into two
-functions, with calls to the Lua string.format function.  One function takes
-only one format specifier, and the other takes two.  
+I have implemented `conky_printf`, a generalized function for printing conky
+data to the output string.  It needs more testing, as I'm sure there are edge
+cases where it doesn't work properly.  
 
-The `fmt()` function takes the format string, and expects a single numerical
-second argument.  If the format string contains any format specifiers (see `man
-sprintf` for details) that aren't numbers (e.g. `%s` for strings), fmt() will
-fail with an error.  I use this for the percentages of RAM, Swap, and CPU in
-use.
-
-The `fmt2()` function takes the format string, and expects two string arguments.
-It is not necessarily an error if either or both of the arguments are numbers,
-they will be cast to strings.  I use this function to format the bandwidth
-("Net:") display in conky, so the length of this segment doesn't shift around
-(the Unicode arrow icons for up and down bandwidth stay in the same place).  
-
-Ideally these two functions would be combined into a `"conky_printf` function,
-that could take an arbitrary format string with any number of format
-specifiers, with the requisite number of numerical or string arguments.  I know
-how to do this with the `...`/`arg`/`unpack(arg)` table specification in Lua,
-but numeric specifiers need to convert any strings passed to the function to
-numeric values instead of strings.  This is the challenging part, but should be
-doable.
+TODO:  Add color to the conky output!  That will take if statments, and text
+for dmenu to consume.
