+ <tag>The .erlang Start-up File</tag>
+ <item>
+ <p>When Erlang/OTP is started, the system searches for a file named .erlang
+ in the directory where Erlang/OTP is started. If not found, the user's home
+ directory is searched for an .erlang file.</p>
+ <p>If an .erlang file is found, it is assumed to contain valid Erlang expressions.
+ These expressions are evaluated as if they were input to the shell.</p>
+ <p>A typical .erlang file contains a set of search paths, for example:</p>
+ <code type="none"><![CDATA[
+ io:format("executing user profile in HOME/.erlang\n",[]).
+ code:add_path("/home/calvin/test/ebin").
+ code:add_path("/home/hobbes/bigappl-1.2/ebin").
+ io:format(".erlang rc finished\n",[]).
+ ]]></code>

+ <tag>user_default and shell_default</tag>
+ <item>
+ <p>Functions in the shell which are not prefixed by a module name are assumed
+ to be functional objects (Funs), built-in functions (BIFs), or belong to the
+ module user_default or shell_default.</p>
+ <p>To include private shell commands, define them in a module user_default and
+ add the following argument as the first line in the .erlang file.</p>
+ <code type="none"><![CDATA[
+ code:load_abs("..../user_default").
+ ]]></code>

+ <tag>erl</tag>
+ <item>
+ <p>If the contents of .erlang are changed and a private version of
+ user_default is defined, it is possible to customize the Erlang/OTP environment.
+ More powerful changes can be made by supplying command line arguments in the
+ start-up script erl. Refer to erl(1) and <seealso marker="init">init(3)</seealso>
