# CVS program sadd
# Program to add the file to CVS

# Every filename is composed of 3 parts - Home directory, sub-directory 
# and the filename. The full-path is $HOME/$subdir/$fname
# And in CVS the same directory structure is maintained (by 
# variable $subdir) therefore in cvs we will have $CVSROOT/$subdir/$fname
# In this program these 4 variables $HOME, $CVSROOT, $subdir and $fname
# play a important role. For example, sample values can be like
# HOME=/home/aldev, subdir=myproject/src CVSROOT=/home/cvsroot 
# and fname=foo.cpp

# Caution: Put double-quotes to protect the variables having 
#          spaces, like "$HOME/$subdir" if subdir is 'some foo.cpp'
