+minimum viable walltaker client based on skalibs.
+(mr skarnet if u see this i am sorry for using your nice systems programming library to make goonware)
+
+simple usage ($ID is your walltaker link id):
+```
+while true; do
+	mvwt $ID
+	sleep 10
+done
+```
+the cachedir can be set with the -c flag;
+the default cachedir is /tmp/mvwt (changeable in config.h)
+the cachedir must already exist, so mkdir it if it doesn't exist already.
+
+build time dependency:
+	a build of skalibs (if you want static compilation, modify the makefile as per the comments)
+runtime dependencies:
+	s6-networking (this program uses ucspi for network communication)
+	hsetroot (used to actually set the wallpaper)
+	
+pdjson.{c,h} is a bundled public domain cjson parser available from here: https://github.com/skeeto/pdjson
+
+you might want to remove the `current` file in the cachedir before every
+time you start using mvwt;
+if the file already exists and your wallpaper is still the same as it
+was before, it won't be set again.
+(this is because mvwt doesn't have any constant internal state,
+it's meant to be run in a cron job or a shell loop and reads `current`
+and compares it to walltaker's API response
+to check if it needs to download and change the wallpaper)
+
+mvwtc and mvwtimg shouldn't be used directly. they expect to be on
+a ucspi connection and are spawned by mvwt.
+
+public domain i guess. do whatever you want with this
