They are usually available as .dvi, +.ps, .pdf, .html or plain text files (sometimes included in the +.sty files instead of a separate documentation file) and can be +accessed with this browser, which is simply an interface to find a +documentation more easily. It starts the respective viewer for +reading the selected documentation making use of a database file +which contains the path entries according to the current teTeX +texmf/doc structure; additional usage of a system-wide local and +of individual user texmf trees with corresponding databases is also +possible. +The documentations are grouped in several categories shown in the +main window; pressing one of its buttons lists all documentations +belonging to this topic. +The topic window lets you select one documentation file, view or +send it to the default printer. By right-clicking on the selected +item you get the complete path of the file. +The search button of the main window allows you to search the +database for a string; it does not search file names. Enter the +string and hit to start the search or to +cancel. Just hitting without typing something in will +show the full list of files in the database. +Defaults for the documentation root directory, the viewers, the +converters, certain options and the printer are set in the global +configuration file $sysrc. +However, each user can put a copy of it as .texdocrc into his home +directory to modify them according to his needs; modification or +generation of ~/.texdocrc can also be done with the Settings menu. +Additionally, the settings can be changed temporarily with this +menu. + +The following key shortcuts are defined for use with the browser: + Quit browser + Raise the Main window to the foreground + Search a keyword in database (case insensitive) + Cancel/close subwindow or search entry widget + View selected document (topic windows) + Print selected document (topic windows) + Open settings menu + Kill fatal error message window (same as + ) + Open this help + Equivalent to button press; + OK in selection menu and search + Next/previous widget + +There are the following command line options: + -a autostart viewer if a listbox of search results + contains only one item; can also be set in a + configuration file + -v disable suppression of viewer messages sent to + stderr and of certain permanent message popup + windows, in case this was not set in a + configuration file; default: off + +Some more information is available in the manpage of texdoctk. + +Comments and suggestions to: +Thomas Ruedas +tr@geol.ku.dk +# Local Variables: +# mode: perl +# auto-fill-hook: do-auto-fill +# End: -- cgit v1.2.3
