+Usage: xpit list [options]
+Examples:
+    xpit list -d , -f TITLE,POST_COUNT
+Options:

+        Defaults to '|' (pipe).
+    -f, --fields <FIELD,...>

+            ID - ID of the issue
+            TITLE - Title of the issue
+            AUTHOR - Author of the issue
+            POST_COUNT - Total number of posts in the issue, including the initial post
+            PATH_ABS - absolute path to issue.md file
+            PATH_REL - relative path to issue.md file
+        Other fields are optional and parsed in issues' INI headers.
+        The fields are printed in order and the same field can be printed more than once.
