-# To do
-
-* migrate this todo list into entomologist
-
-* implement user control over state transitions
-
-* implement `ent comment ${ISSUE} [-m ${MESSAGE}]`
-    - each issue dir has a `comments` subdir
-    - each comment is identified by a sha1-style uid
-    - each comment is a file or directory under the `${ISSUE}/comments`
-    - comments are ordered by ctime?
-
-* implement `ent edit ${COMMENT}`
-
-* implement `ent attach ${ISSUE} ${FILE}`
-    - each issue has its own independent namespace for attached files
-    - issue description & comments can reference attached files via standard md links
-
-* write a manpage
