+cgit - CGI for Git
+==================

 
 

-                       cgit - cgi for git
+This is an attempt to create a fast web interface for the Git SCM, using a
+built-in cache to decrease server I/O pressure.

 
 

+Installation
+------------

 
 

-This is an attempt to create a fast web interface for the git scm, using a
-builtin cache to decrease server io-pressure.
+Building cgit involves building a proper version of Git. How to do this
+depends on how you obtained the cgit sources:

 
 

+a) If you're working in a cloned cgit repository, you first need to
+initialize and update the Git submodule:

 
 

-Installation
+    $ git submodule init     # register the Git submodule in .git/config
+    $ $EDITOR .git/config    # if you want to specify a different url for git
+    $ git submodule update   # clone/fetch and checkout correct git version

 
 

-  $ make gitsrc=<path>
-  $ su
-  $ make prefix=<path> install
+b) If you're building from a cgit tarball, you can download a proper git
+version like this:

 
 

+    $ make get-git

 
 

-Default value for gitsrc is "../git", and this directory should contain the
-git sources.
+When either a) or b) has been performed, you can build and install cgit like
+this:

 
 

-Default value for prefix is "/var/www/htdocs/cgit". This directory will 
-contain "cgit.cgi" and "cgit.css" after 'make install'.
+    $ make
+    $ sudo make install

 
 

-After installation, httpd.conf probably must be updated with a Directory-
-section for cgit, possibly something like this:
+This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
+can configure this location (and a few other things) by providing a `cgit.conf`
+file (see the Makefile for details).

 
 

-  <Directory "/var/www/htdocs/cgit/">
-      AllowOverride None
-      Options ExecCGI
-      Order allow,deny
-      Allow from all
-  </Directory>
+If you'd like to compile without Lua support, you may use:

 
 

+    $ make NO_LUA=1

 
 

-Runtime configuration
+And if you'd like to specify a Lua implementation, you may use:
+
+    $ make LUA_IMPLEMENTATION=JIT
+
+for using the LuaJIT project. Or:
+
+    $ make LUA_IMPLEMENTATION=VANILLA
+
+for the mainline Lua project. If you specify neither implementation, it will
+be auto-detected, preferring LuaJIT if both are present.
+
+
+Dependencies
+------------

 
 

-The file /etc/cgitrc is read by cgit before handling a request. In addition
-to runtime parameters, this file also contains a list of the repositories 
-displayed by cgit.
+* libzip
+* libcrypto (OpenSSL)
+* libssl (OpenSSL)
+* optional: luajit or lua

 
 

-A template cgitrc is shipped with the sources, and all parameters and default
-values are documented in this file. 
+Apache configuration
+--------------------

 
 

+A new `Directory` section must probably be added for cgit, possibly something
+like this:
+
+    <Directory "/var/www/htdocs/cgit/">
+        AllowOverride None
+        Options +ExecCGI
+        Order allow,deny
+        Allow from all
+    </Directory>

+to runtime parameters, this file may also contain a list of repositories
