SUBROUTINES

find_file

Try to locate a file whose name is created from the $default_start and all elements of @names. If it does not exist, try to replace the $default_start by elements of @INC (one by one). If neither of them points to an existing file, go back and return the $default_start and all elements of @names (even - as we know now - such file does not exist).

There are two or more arguments: $default_start and @names.

getHttpRequestByURL

returns a scalar of text obtained from the url or dies if there was no success

empty_rdf

returns a string of RDF that represents a syntactically correct RDF file

trim

trims whitespace from the begining and end of a string
