more­help – Im­prove LaTeX er­ror mes­sages

The pack­age en­hances LaTeX2ε er­ror mes­sages by pro­vid­ing de­scrip­tions of the pos­si­ble causes in­clud­ing those that may not be ob­vi­ous. This style is ef­fec­tively an on­line sub­sti­tute for er­ror lists found in the LaTeX books, al­though it can­not com­pletely re­place them. Only true LaTeX er­rors are in­cluded: TeX er­rors are be­yond the reach of or­di­nary macros.
