OVERVIEW +II. REMARKS ON THIS RELEASE +II. CHANGE LOG + +======================================================================== +I. OVERVIEW + +Complete documentation of all package options is available in +snapshot.pdf. + +Typical usage involves the following steps: + +1. Add a \RequirePackage statement at the top of the document: + + \RequirePackage{snapshot} + \documentclass{article} + + \usepackage{graphicx} + + \begin{document} + + hello, world + + \end{document} + + Note that snapshot should be the very first thing loaded, even + before the \documentclass. Otherwise snapshot will not be able to + capture the information for the document class and any packages + loaded inside it. + +2. Run LaTeX on the document. This will produce a dependency list in a + file \jobname.dep. + +3. Insert the .dep file at the top of the document, before + \documentclass. The following example shows what you would + typically end up with for a document that used the article + documentclass and the graphicx package: + + \RequirePackage{snapshot} + + \RequireVersions{ + *{application}{pdfTeX} {0000/00/00 v1.40.21} + *{format} {LaTeX2e} {2020-02-02 v2.e} + *{package}{snapshot} {2020/06/17 v2.14} + *{class} {article} {2019/12/20 v1.4l} + *{file} {size10.clo} {2019/12/20 v1.4l} + *{package}{graphicx} {2019/11/30 v1.2a} + *{package}{keyval} {2014/10/28 v1.15} + *{package}{graphics} {2019/11/30 v1.4a} + *{package}{trig} {2016/01/03 v1.10} + *{file} {graphics.cfg}{2016/06/04 v1.11} + *{file} {dvips.def} {2017/06/20 v3.1d} + *{file} {l3backend-dvips.def}{2020-05-05 v3} + } + + \documentclass{article} + [...] + + Now each time you recompile the document, snapshot will compare the + list of files actually loaded against the list recorded in + \RequireVersions and warn you of any changes. + +======================================================================== +II. REMARKS ON THIS RELEASE + +Since the snapshot package was originally released, there has been a +tremendous amount of evolution among TeX engines (what snapshot calls +the "application"). In addition to the introduction of two major new +engines, three other engines that were once distinct have effectively +merged. The algorithm for detecting the identify of the engine has +been updated to reflect the state of the TeX world as reflected in TeX +Live 2020. + +COMPATIBILITY NOTE: As a result of these improvements, the +*{application} entry of your documents will almost certainly change. +The snapshot package does not warn of changes in this entry, but if +you have an external application that makes use of this information, +you will probably need to update it. + +======================================================================== +III.
