+
+This is the ledger filetype for vim.
+Copy each file to the corresponding directory in your ~/.vim directory.
+Then include the following line in your .vimrc or in ~/.vim/filetype.vim
+ au BufNewFile,BufRead *.ldg,*.ledger setf ledger
+You can also use a modeline like this in every ledger file
+ vim:filetype=ledger
+
+Configuration
+======================================================================
+Include the following let-statements somewhere in your .vimrc
+to modify the behaviour of the ledger filetype.
+
+* Number of colums that will be used to display the foldtext.
+ Set this when you think that the amount is too far off to the right.
+ let g:ledger_maxwidth = 80
+
+* String that will be used to fill the space between account name
+ and amount in the foldtext. Set this to get some kind of lines
+ or visual aid.
+ let g:ledger_fillstring = ' -'
+ My special tip is to use so-called digraphs:
+ Press <C-K> followed by the two-characters key sequence below.
+ (in insert-mode)
+ '. = ˙ or ': = ¨ --> ˙˙˙˙˙˙ or ¨¨¨¨¨¨
+ ', = ¸ --> ¸¸¸¸¸¸
+ .M = · --> ······
+ >> = » --> »»»»»»
+ All those look rather unobstrusive
+ and provide a good visual aid to find the correct amount.
+
+* If you want the account completion to be sorted by level of detail/depth
+ instead of alphabetical, include the following line:
+ let g:ledger_detailed_first = 1
+
+Completion
+======================================================================
+Omni completion is implemented for account names and tags.
+
+Accounts
+----------------------------------------------------------------------
+Account names are matched by the start of every sub-level.
+When you insert an account name like this:
+ Asse<C-X><C-O>
+You will get a list of top-level accounts that start like this.
+
+Go ahead and try something like:
+ As:Ban:Che<C-X><C-O>
+When you have an account like this, 'Assets:Bank:Checking' should show up.
+
+When you want to complete on a virtual transaction,
+it's currently best to keep the cursor in front of the closing bracket.
+Of course you can insert the closing bracket after calling the completion, too.
+
+Tags
+----------------------------------------------------------------------
+The support for completing tags is pretty basic right now
+but it's useful to keep the spelling of your tags consistent.
+You can call the completion after the ';' to get a list of all tags.
+When you have a list of tags (:like: :this:) you can call
+the completion too and everything up to the last ':' (excluding whitespace)
+will be considered the beginning of the tag to search for.
+
+Revision history (major changes)
