+# sdlfmt
+
+```
+Auto-formatter for SDLang files
+Usage:
+        sdlfmt [OPTIONS...] [--] FILENAMES...
+
+ General options:
+-i --inplace Edit files in place
+-h    --help This help information.
+
+Formatter options:
+                  --end_of_line (lf|cr|crlf)
+-t               --indent_style (tab|space)
+                  --indent_size (default = 1 for tab, 4 for space)
+     --whitespace_around_equals (default = false)
+   --backslash_temp_indent_size (default = 2)
+
+Use - as only file name if you want to read from stdin
+
+By default, only a single file can be passed in as input and the formatted
+output will be dumped to stdout. Use --inplace to be able to specify multiple
+input files.
