+## winter is near
+- given is an simple ascii text file with the lyrics of "we wish you a merry christmas" and a bunch of whitespace in it.
+- on first thought I tried executing it as the Whitespace programming language, it writes a bunch of data to the stack but when printing it to stout you just get a bunch of gibberish.
+- In retrospect I find out that it must be solved with the snow.exe or stegsnow utility which then after a simple command prints out the flag:
+```bash
+# uncompress whitespace:
+stegsnow -C winter.txt
+```
+
