 =head1 NAME
 
 dbicdump - Dump a schema using DBIx::Class::Schema::Loader
 
 =head1 SYNOPSIS
 
-  dbicdump [-o <loader_option>=<value> ] <schema_class> <connect_info>
+    dbicdump <configuration_file>
+    dbicdump [-I <lib-path>] [-o <loader_option>=<value> ] \
+             <schema_class> <connect_info>
 
 Examples:
 
-  $ dbicdump -o dump_directory=./lib \
-    -o components='["InflateColumn::DateTime"]' \
-    MyApp::Schema dbi:SQLite:./foo.db '{ quote_char => "\"" }'
+    $ dbicdump schema.conf
+
+    $ dbicdump -o dump_directory=./lib \
+      -o components='["InflateColumn::DateTime"]' \
+      MyApp::Schema dbi:SQLite:./foo.db
+
+    $ dbicdump -o dump_directory=./lib \
+      -o components='["InflateColumn::DateTime"]' \
+      MyApp::Schema dbi:SQLite:./foo.db '{ quote_char => "\"" }'
+
+    $ dbicdump -Ilib -o dump_directory=./lib \
+      -o components='["InflateColumn::DateTime"]' \
+      -o preserve_case=1 \
+      MyApp::Schema dbi:mysql:database=foo user pass \
+      '{ quote_char => "`" }'
 
-  $ dbicdump -o dump_directory=./lib \
-    -o components='["InflateColumn::DateTime"]' \
-    -o preserve_case=1 \
-    MyApp::Schema dbi:mysql:database=foo user pass '{ quote_char => "`" }'
+    $ dbicdump -o dump_directory=./lib \
+      -o components='["InflateColumn::DateTime"]' \
+      MyApp::Schema 'dbi:mysql:database=foo;host=domain.tld;port=3306' \
+      user pass
 
 On Windows that would be:
 
-  $ dbicdump -o dump_directory=.\lib ^
-    -o components="[q{InflateColumn::DateTime}]" ^
-    -o preserve_case=1 ^
-    MyApp::Schema dbi:mysql:database=foo user pass "{ quote_char => q{`} }"
+    $ dbicdump -o dump_directory=.\lib ^
+      -o components="[q{InflateColumn::DateTime}]" ^
+      -o preserve_case=1 ^
+      MyApp::Schema dbi:mysql:database=foo user pass ^
+      "{ quote_char => q{`} }"
+
+Configuration files must have schema_class and connect_info sections,
+an example of a general config file is as follows:
+
+    schema_class MyApp::Schema
+
+    lib /extra/perl/libs
+
+    # connection string
+    <connect_info>
+        dsn     dbi:mysql:example
+        user    root
+        pass    secret
+    </connect_info>
+
+    # dbic loader options
+    <loader_options>
+        dump_directory ./lib
+        components     InflateColumn::DateTime
+        components     TimeStamp
+    </loader_options>
+
+Using a config file requires L<Config::Any> installed.
+
+The optional C<lib> key is equivalent to the C<-I> option.
