// Search & replace patterns for conversion from LaTeX/BibTeX markup & entities to refbase markup. Converts LaTeX fontshape markup (italic, bold, underline)
|
|
// into appropriate refbase commands, super- and subscript as well as greek letters in math mode get converted into the respective refbase commands.
|
|
// You may need to adopt the LaTeX markup to suit your individual needs.
|
|
// Notes: - search & replace patterns must be specified as perl-style regular expression and search patterns must include the leading & trailing slashes
