+/* 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).
