#   NAME
#   acsMakeInstallFiles - copy the files into target area.
# 
#   SYNOPSIS
#
#   acsMakeInstallFiles <fileList> <PRJTOP> <ACSTARGET> <protectionMask>
#
# 
#   DESCRIPTION
#   Utility used by acsMakefile to generate the acsMakefile.install section
#   in charge to copy the files into target area.
#   For every file in <fileList>:
#
#      - get "name" and "dir", i.e.: the filename and the parent directory
#
#      - the rule to copy the file into PRJTOP/<dir> or in ACSTARGET/<dir>
#        is generated. As for any installed file, the rule is executed only if
#        the file is newer. The protection mask is applied to leave the file 
#        overwritable by the next installation
#
#
#   It is not intended to be used as a standalone command.
#
#   <fileList>        file to be copied
#   <PRJTOP>          starting point for bin, include, etc (ACS|INT-ROOT[/vw])
#   <ACSTARGET>       starting point for other directories (ACS|INT-ROOT)
#   <protectionMask>  how to set the protection of created file
#
#
#   FILES
#   $ACSROOT/include/acsMakefile   
#
#   ENVIRONMENT
#
#   RETURN VALUES
