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
