<div><h1>initialization file</h1>
<div>The file <tt>init.m2</tt> is loaded automatically when the program is started, if it exists.<p>On most systems the file is sought in the directory <tt>$HOME/.Macaulay2/</tt>, where <tt>$HOME</tt> is replaced by the path to the user's home directory.</p>
<p>Under Mac OS X, the file is sought instead in the directory <tt>$HOME/Library/Application Support/Macaulay2/</tt>.</p>
<p>If the user wants a file called, say, <tt>start.m2</tt> in the current directory to be loaded automatically when the program is started, then the following line of code can be placed in the file <tt>init.m2</tt>.</p>
<pre>if fileExists "start.m2" then load(currentDirectory()|"start.m2")</pre>
<p>Warning: former versions of the program would also load a file named <tt>init.m2</tt> found in the current directory.</p>
