If it does not exist, cb2Bib will create one 285 based on predefined defaults. 286 -If starting cb2Bib from a removable media, use the command 'cb2bib --conf' without configuration 287 filename. Settings will be read from and written to /cb2bib/full/path/cb2bib.conf, being therefore 288 independent of the mounting address that the host computer will provide. 289 -To import references from a browser select when asked c2bimport, which expands to 'cb2bib --import %f'. 290 The browser will provide the temporary reference filename. 291 -A number of factors influence the reliability of automatic extractions. Consider writing customized 292 regular expressions and network queries, and use metadata when available. 293 294 Important: 295 -The commands --doc2bib and --txt2bib do not append the references to the references.bib.
