# prepare_getLinkName.sh -- This function standardizes link name

# construction. For the construction sake, two arguments are required,

# one to now the file's base directory, and another holding the file's

# absolute path. With this information, the base directory is removed

# from file's absolute path and the remaining path is transformed into

# a file name where each slash is converted into minus sign. 

# 

# For example, if the following information is provided:

#

# ARG1: /home/centos/artwork/trunk/Identity/Brushes

# ARG2: /home/centos/artwork/trunk/Identity/Brushes/Corporate/symbol.gbr

#

# the result will be: `corporate-symbol.gbr'.
