* If necessary, it can be the tex file that originated the synctex file
* but this might cause problems if the \jobname has a custom value.
* Despite this method can accept a relative path in practice,
* you should only pass a full path name.
* The path should be encoded by the underlying file system,
* assuming that it is based on 8 bits characters, including UTF8,
* not 16 bits nor 32 bits.
* The last file extension is removed and replaced by the proper extension.
* Then the private method _synctex_scanner_new_with_contents_of_file is called.
* NULL is returned in case of an error or non existent file.
* Once you have a scanner, use the synctex_display_query and synctex_edit_query below.
* The new "build_directory" argument is available since version 1.5.
* It is the directory where all the auxiliary stuff is created.
* Sometimes, the synctex output file and the pdf, dvi or xdv files are not created in the same directory.
* This is the case in MikTeX (I will include this into TeX Live).
* This directory path can be nil, it will be ignored then.
* It can be either absolute or relative to the directory of the output pdf (dvi or xdv) file.
* If no synctex file is found in the same directory as the output file, then we try to find one in the build directory.
* Please note that this new "build_directory" is provided as a convenient argument but should not be used.
* In fact, this is implempented as a work around of a bug in MikTeX where the synctex file does not follow the pdf file.
* The new "parse" argument is available since version 1.5. In general, use 1.
* Use 0 only if you do not want to parse the content but just check the existence.
