+  save and set aside changes from the working directory
+  
+      Shelving takes files that "hg status" reports as not clean, saves the
+      modifications to a bundle (a shelved change), and reverts the files so
+      that their state in the working directory becomes clean.
+  
+      To restore these changes to the working directory, using "hg unshelve";
+      this will work even if you switch to a different commit.
+  
+      When no files are specified, "hg shelve" saves all not-clean files. If
+      specific files or directories are named, only changes to those files are
+      shelved.
+  
+      Each shelved change has a name that makes it easier to find later. The
+      name of a shelved change defaults to being based on the active bookmark,
+      or if there is no active bookmark, the current named branch.  To specify a
+      different name, use "--name".
+  
+      To see a list of existing shelved changes, use the "--list" option. For
+      each shelved change, this will print its name, age, and description; use "
+      --patch" or "--stat" for more details.
+  
+      To delete specific shelved changes, use "--delete". To delete all shelved
+      changes, use "--cleanup".
+  
+  (use "hg help -e shelve" to show help for the shelve extension)
+  
+  options ([+] can be repeated):
+  
+   -A --addremove           mark new/missing files as added/removed before

+      --cleanup             delete all shelved changes
+      --date DATE           shelve with the specified commit date
+   -d --delete              delete the named shelved change(s)
+   -e --edit                invoke editor on commit messages
+   -l --list                list current shelves
+   -m --message TEXT        use text as shelve message
+   -n --name NAME           use the given name for the shelved commit
+   -p --patch               show patch
+   -i --interactive         interactive mode, only works while creating a shelve
+      --stat                output diffstat-style summary of changes
+   -I --include PATTERN [+] include names matching the given patterns
+   -X --exclude PATTERN [+] exclude names matching the given patterns
+      --mq                  operate on patch repository

+  (some details hidden, use --verbose to show complete help)

 shelving in an empty repo should be possible
 (this tests also that editor is not invoked, if '--edit' is not
 specified)
