README_src.txt for version 7.3 of Vim: Vi IMproved. The source archive contains the files needed to compile Vim on Unix systems. It is packed for Unix systems (NL line separator). It is also used for other systems in combination with the extra archive (vim-7.3-extra.tar.gz, in the "extra" directory of ftp.vim.org). For more information, see the README.txt file that comes with the runtime archive (vim-7.3-rt.tar.gz). To be able to run Vim you MUST get the runtime archive too!
