-# Simple C mode for Emacs
-
-Because whatever comes with Emacs is too slow.
-
-This mode does not try to be as featureful as `c-mode`, `c++-mode`,
-`cc-mode`, etc. Instead we are trying to implement a bare minimum
-syntax highlighting and indentation to maintain high performance on
-big files with long lines.
-
-The goal is to be able to comfortably browse and modify the following files:
-- [imgui](https://raw.githubusercontent.com/ocornut/imgui/fb7f6cab8c322731da336e553915e944bf386e62/imgui.h)
-- [amalgamated sqlite3.c](https://raw.githubusercontent.com/IreneKnapp/direct-sqlite/a74cc50c735053c7c49c487a66e7756b524db883/cbits/sqlite3.c)
-- [miniaudio.h](https://raw.githubusercontent.com/mackron/miniaudio/refs/heads/master/miniaudio.h)
-- ...
-
-Right now the only way to work with these files in Emacs is to use
-`text-mode`. Which is actually a good evidence that Emacs itself can
-handle such files! It's `c-mode` (and others) that cannot.
-
-## Installing locally
-
-Put [simpc-mode.el](./simpc-mode.el) to some folder `/path/to/simpc/`. Add this to your `.emacs`:
-
-```el
-;; Adding `/path/to/simpc` to load-path so `require` can find it
-(add-to-list 'load-path "/path/to/simpc/")
-;; Importing simpc-mode
-(require 'simpc-mode)
-;; Automatically enabling simpc-mode on files with extensions like .h, .c, .cpp, .hpp
-(add-to-list 'auto-mode-alist '("\\.[hc]\\(pp\\)?\\'" . simpc-mode))
-```
-
-## Indentation
-
-Right now the mode supports only very simple indentations based on the
-analysing the previous non-empty line and its surrounding curly
-braces. Anything more complicated is outside of the scope of the
-project.
-
-It is recommended to use an external formatter such as
-[indent](https://www.gnu.org/software/indent/),
-[astyle](http://astyle.sourceforge.net/),
-[clang-format](https://clang.llvm.org/docs/ClangFormat.html), etc.
-
-Here is how I use [astyle](http://astyle.sourceforge.net/):
-
-```emacs-lisp
-(defun astyle-buffer ()
- (interactive)
- (let ((saved-line-number (line-number-at-pos)))
- (shell-command-on-region
- (point-min)
- (point-max)
- "astyle --style=kr"
- nil
- t)
- (goto-line saved-line-number)))
-```
-
-Then I bind `astyle-buffer` to some key combination and invoke it
-periodically to reformat the whole current buffer.
