+/* gitignore - Filter for intentionally untracked lines or blocks of code
+
+This is a filter that allows specifying intentionally untracked lines and
+blocks of code that Git should ignore.
+
+Example:
+
+  int main(void) {
+    printf("I would never say derp.\n");
+    //#gitignore-begin
+    printf("DERP!\n");
+    //#gitignore-end
+    printf("DERP!\n"); //#gitignore
+    return 0;
+  }
+
+Installation:
+
+  Define a filter, e.g. in ~/.config/git/config[1]:
+
+      [filter "gitignore"]
+        clean = gitignore
+        smudge = cat
+
+  Assing that filter to some paths, e.g. in ~/.config/git/attributes[2]:
+
+      *.hs filter=gitignore
+      *.c filter=gitignore
+      ...
+
+  [1]: For more information about defining filters see git-config(1).
+  [2]: For more information about assigning filters see gitattributes(5).
