Version 2.4 This bundle provides two classfiles, namely cas-sc.cls and cas-dc.cls and corresponding template files for typesetting journal articles supposed to go through Elsevier's updated workflow. cas-sc.cls is meant for one-column, the other cas-dc.cls for two-column layout. These are now accepted for submitting articles both in Elsevier's electronic submission system and elsewhere. Bugs and problems with classfiles may be reported to the developers of the class via elsarticle@stmdocs.in. The file manifest.txt provides a list of the files in the elsarticle-cas bundle. The following are the main files available: - cas-sc.cls, classfile to typeset article in single column - cas-dc.cls, classfile to typeset article in double column - cas-sc-template.tex, template file for single column journals - cas-dc-template.tex, template file for double column journals - cas-common.sty, additional macro package for formatting - cas-model2-names.bst, BibTeX style file - cas-refs.bib, sample BibTeX database - cas-twitter.jpeg, cas-linkedin.jpeg, cas-url.jpeg, cas-gplus.jpeg, cas-facebook.jpeg, cas-email.jpeg - thumbnail images of social networking sites The PDF documentation elsdoc-cas.pdf is in the doc directory. To generate it: 1. pdflatex elsdoc-cas 2. pdflatex elsdoc-cas 3. pdflatex elsdoc-cas or use the makefile. Use the target `all' (eg: make all) in doc directory.
