#  Script:  strip_c_copyright.pl
#
#  Purpose: This script removes a copyright header from a c/c++
#           file. The file is passed into the perl script via STDIN, so this
#           script must be used in conjunction with something like 'cat'.
#
#  Usage:   cat <file> | ./strip_c_copyright.pl
#
#
#  Previous attemps at c-style regular expressions...
#    s#(?:\/\*(?:[^*]|(?:\*+[^*\/]))*\*+\/).*\n##;
#    s#(?:\/\*.*Copyright\(c\)(?:[^*]|(?:\*+[^*\/]))*\*+\/).*\n|(?:\/\*(?:[^*]|(?:\*+[^*\/]))*Copyright\(c\)(?:[^*]|(?:\*+[^*\/]))*\*+\/).*\n##;
#    good => s#(?:\/\*.*Copyright(?:[^*]|(?:\*+[^*\/]))*\*+\/).*\n|(?:\/\*(?:[^*]|(?:\*+[^*\/]))*Copyright(?:[^*]|(?:\*+[^*\/]))*\*+\/).*\n##;
#    good => s#(?:\/\*.*Copyright(?:[^*]|(?:\*+[^*\/]))*\*+\/).*(?:\s)+|(?:\/\*(?:[^*]|(?:\*+[^*\/]))*Copyright(?:[^*]|(?:\*+[^*\/]))*\*+\/).*(?:\s)+##;
#
#  The following regex can be used for removing redundant C++
#  copyright header from libssd files...
