Brief Pacman Installation Instruction

1. Take latest Pacman and install it :

   Create somewhere directory  software/ and simply untar Pacman there :

  	cd software

   	wget http://physics.bu.edu/pacman/sample_cache/tarballs/pacman-latest.tar.gz
   	tar xzf pacman-latest.tar.gz
  	# It will be created, for example, directory pacman-3.21/
  	rm -f pacman-latest.tar.gz
      	ln -s pacman-* pacman	
      	cd pacman
   	source setup.csh # or setup.sh
   	cd ..

2. Now you may play with Pacman :


   	pacman -help      
   	pacman -v help    
 
3. If you know your Linux distribution, you may set it up now.
   
   First see list of all supported platforms :
   
   	pacman -platforms
   
   Example for SLC-4.5 :
  
   	pacman -pretend-platform CERN-SL-4

----
Using Pacman

 One unusual thing about Pacman is that the command line switches -d, -v, -allow, -ask and -setups 
 are "sticky". For instance, if you do

	pacman -allow tar-overwrite

this setting remains as a default until you change it. Use

	pacman -def

to see your current default switch values. 

	pacman -history

	pacman -platforms  gives the complete list of platforms.


	pacman -version

	pacman -domain

and you will see all parts of your system Pacman has modified or is keeping track of. 

To remove software correctly, use, for example,

	pacman -remove

This removes all packages from your installation recursively. 
See pacman -help   for more details.


Do detailed test:

	pacman -d cmp -l Ready
