+"gimprc \\- gimp configuration file\n"
+".SH DESCRIPTION\n"
+"The\n"
+".B gimprc\n"
+"file is a configuration file read by GIMP when it starts up.  There\n"
+"are two of these: one system-wide one stored in\n"
+"@gimpsysconfdir@/gimprc and a per-user @manpage_gimpdir@/gimprc\n"
+"which may override system settings.\n"
+"\n"
+"Comments are introduced by a hash sign (#), and continue until the end\n"
+"of the line.  Blank lines are ignored.\n"
+"\n"
+"The\n"
+".B gimprc\n"
+"file associates values with properties.  These properties may be set\n"
+"by lisp-like assignments of the form:\n"
+".IP\n"
+"\\f3(\\f2property\\-name\\ value\\f3)\\f1\n"
+".TP\n"
+"where:\n"
+".TP 10\n"
+".I property\\-name\n"
+"is one of the property names described below.\n"
+".TP\n"
+".I value\n"
+"is the value the property is to be set to.\n"
+".PP\n"
+"\n"
+"Either spaces or tabs may be used to separate the name from the value.\n"
+".PP\n"
+".SH PROPERTIES\n"
+"Valid properties and their default values are:\n"
+"\n";
+
+static const gchar *man_page_path =
+".PP\n"
+".SH PATH EXPANSION\n"
+"Strings of type PATH are expanded in a manner similar to\n"
+".BR bash (1).\n"
+"Specifically: tilde (~) is expanded to the user's home directory. Note that\n"
+"the bash feature of being able to refer to other user's home directories\n"
+"by writing ~userid/ is not valid in this file.\n"
+"\n"
+"${variable} is expanded to the current value of an environment variable.\n"
+"There are a few variables that are pre-defined:\n"
+".TP\n"
+".I gimp_dir\n"
