text: XSLT::Dependencies - Finds all the files included or imported by particular XSLT
  use XSLT::Dependencies; my $dep = new XSLT::Dependencies; my @dep_list = XSLT::Dependencies->explore('myfile.xslt');
  XSLT::Dependencies builds a list of all the files included or imported by a given XSTL one. Recursive dependencies always result in a flattened list.
  XSLT::Dependencies scans the given XSTL file and all the files it includes by
  xsl:include or
  xsl:import directives.
  Creates a new instance of XSLT::Dependencies object.
  my $dep = new XSLT::Dependencies;
  Scans a file together with all its dependencies and returns a list of absolute paths for every dependent file.
  my @dep_list = XSLT::Dependencies->explore('myfile.xslt');
  Resultant list does not include the path to the top-level file for which
  explore was called. If some file is included more then once, it gives a single item in the result. The list is not sorted in any way.
  Note that version 0.2 does not follow any non-standard namespace scheme except
  xsl:.
  The idea behind XSLT::Dependencies was to find all the files that are used to create the final XSLT transformation tree and take a decision whether you need to refresh cached version of the main one.
