TeX/LaTeX is the standard in typesetting research papers in physics. But many my colleges (and myself) were a little unhappy about the appearance of \cal letters (\mathcal in LaTeX 2e). The shape of these characters is very different from typefaces normally used in physical journals and books. With the appearance of Ralph Smith's rsfs fonts and NFSS this problem can be easily resolved. Just put files `OMSrsfs.fd' and `calrsfs.sty' in LaTeX 2e input directory. The command \usepackage{calrsfs} in the preamble of LaTeX file replaces all \mathcal letters by nice letters of rsfs's font and you can enjoy `standard' shape of Lagrangian ... The METAFONT sources of rsfs fonts are available in CTAN in the directory /tex-archive/fonts/rsfs Vadim V. Zhytnikov (vvzhy@phy.ncu.edu.tw)
