" @(#)	This is vimrc for vim/gvim.
"		This vimrc file will automatically configure itself based on
"		the system it runs on (Windows/Unix).
"		This vimrc file has been tested on SPARC/Solaris, Intel/Linux
"		and Windows NT/ME
"
"		Config Notes:
"		Unix:
"			1. Create a directory: ~/vimtmp and move .viminfo there
"			2. Link: ln -s .vimrc .gvimrc	
"			3. If gvim is executed, .vimrc will be executed twice.
"			   First as .vimrc and then as .gvimrc. This is good!
"		Windows:
"			1. Create a directory: $HOME\vimtmp
"			2. Move .viminfo (if it exists) to $HOME\vimtmp	
"			3. Name .vimrc as _vimrc in $HOME 	
"
"			   Make sure there is no _gvimrc in $HOME. This creates a conflict.	
"			4. Optional. In the Windows Global settings below, change the preferences
"			   to suit your needs.
