fithesis3/README

+# About #
+
+`Fithesis3` is a document class for the typesetting of theses at
+the Masaryk University (Brno, Czech Republic). The class has been
+designed for easy extensibility by style and locale files of other
+academic institutions.
+
+# Installation #
+## Requirements ##
+
+To install the package, you are going to need a POSIX.2-compliant
+environment as well as the following tools:
+
+  * GNU `make`
+  * `epstopdf`
+
+Aside from these tools, the installation requires a correctly
+configured TeX distribution containing the pdfTeX and XeTeX engines
+as well as the LaTeX packages required for the typesetting of the
+technical documentation within the `fithesis.dtx` file and the
+guide files within the `guide/` subdirectory.
+
+## Procedure ##
+
+To begin the installation, execute the following command from within
+the current directory:
+
+  make complete install to=[[TDS]] nohash=true
+
+and replace [[TDS]] with a path to the TeX directory structure into
+which you want to install the package (such as `/usr/share/texmf`).
+If necessary, update the file name database of your TeX
+distribution:
+
+  * In MiKTeX:
+    - Using the GUI: In the Start Menu go to the MiKTeX entry and
+      open either the settings or the admin settings depending on
+      whether you are installing the package into a single-user
+      private directory tree or into a shared directory tree on a
+      multi-user system, respectively. The "MiKTeX Options" window
+      will open. Switch to the "General" tab and click the "Refresh
+      FNDB" button.
+    - Using the command prompt: Execute either `initexmf -u` or
+      `initexmf -u --admin` depending on whether you are installing
+      the package into a single-user private directory tree or into
+      a shared shared directory tree on a multi-user system,
+      respectively.
+  * In TeX Live:
+    - Execute `texhash` with superuser privileges (`sudo texhash`).
+
+To uninstall the package, execute the following command from within
+the current directory:
+
+  make uninstall from=[[TDS]] nohash=true
+
+and replace [[TDS]] with a path to the TeX directory structure into
+which you want to install the package (such as `/usr/share/texmf`).
+If necessary, update the file name database of your TeX
+distribution.
