# run vim if:

# - 'vim' command is used

# NOTE: Set up a local alias if you want vim -> vi functionality. We will not

# do it globally, because it messes up with available startup options (see 

# ':help starting', 'vi' is not capable of '-d'). The introducing an environment

# variable, which an user must set to get the feature, will do the same trick

# as setting an alias (needs user input, does not work with sudo), so it is left

# on user whether he decides to use an alias:

#

# alias vim=vi

#

# in bashrc file.
