+=head1 NAME
+
+Apache::TestConfig -- Test Configuration setup module
+
+=head1 SYNOPSIS
+
+ use Apache::TestConfig;
+
+ my $cfg = Apache::TestConfig->new(%args)
+ my $fh = $cfg->genfile($file);
+ $cfg->writefile($file, $content);
+ $cfg->gendir($dir);
+ ...
+
+=head1 DESCRIPTION
+
+C<Apache::TestConfig> is used in creating the C<Apache::Test>
+configuration files.
+
+=head1 FUNCTIONS
+
+=over
+
+=item genwarning()
+
+ my $warn = $cfg->genwarning($filename)
+
+genwarning() returns a warning string as a comment, saying that the
+file was autogenerated and that it's not a good idea to modify this
+file. After the warning a perl trace of calls to this this function is
+appended. This trace is useful for finding what code has created the
+file.
+
+ my $warn = $cfg->genwarning($filename, $from_filename)
+
+If C<$from_filename> is specified it'll be used in the warning to tell
+which file it was generated from.
+
+genwarning() automatically recognizes the comment type based on the
+file extension. If the extension is not recognized, the default C<#>
+style is used.
+
+Currently it support C<E<lt>!-- --E<gt>>, C</* ... */> and C<#>
+styles.
+
+=item genfile()
+
+ my $fh = $cfg->genfile($file);
+
+genfile() creates a new file C<$file> for writing and returns a file
+handle.
+
+If parent directories of C<$file> don't exist they will be
+automagically created.
+
+The file C<$file> and any created parent directories (if found empty)
+will be automatically removed on cleanup.
+
+A comment with a warning and calls trace is added to the top of this
+file. See genwarning() for more info about this comment.
+
+ my $fh = $cfg->genfile($file, $from_file);
+
+If C<$from_filename> is specified it'll be used in the warning to tell
+which file it was generated from.
+
+ my $fh = $cfg->genfile($file, $from_file, $nowarning);
+
+If C<$nowarning> is true, the warning won't be added. If using this
+optional argument and there is no C<$from_file> you must pass undef as
+in:
+
+ my $fh = $cfg->genfile($file, undef, $nowarning);
+
+
+=item writefile()
+
+ $cfg->writefile($file, $content, [$nowarning]);
+
+writefile() creates a new file C<$file> with the content of
+C<$content>.
+
+A comment with a warning and calls trace is added to the top of this
+file unless C<$nowarnings> is passed and set to a true value. See
+genwarning() for more info about this comment.
+
+If parent directories of C<$file> don't exist they will be
+automagically created.
+
+The file C<$file> and any created parent directories (if found empty)
+will be automatically removed on cleanup.
+
+=item write_perlscript()
+
+ $cfg->write_perlscript($filename, @lines);
+
+Similar to writefile() but creates an executable Perl script with
+correctly set shebang line.
+
+=item gendir()
+
+ $cfg->gendir($dir);
+
+gendir() creates a new directory C<$dir>.
+
+If parent directories of C<$dir> don't exist they will be
+automagically created.
+
+The directory C<$dir> and any created parent directories will be
+automatically removed on cleanup if found empty.
+

+
+=head1 Environment Variables
+
+The following environment variables affect the configuration and the
+run-time of the C<Apache::Test> framework:
+
+=head2 APACHE_TEST_COLOR
+
+To aid visual control over the configuration process and the run-time
+phase, C<Apache::Test> uses coloured fonts when the environment
+variable C<APACHE_TEST_COLOR> is set to a true value.
+
+=head2 APACHE_TEST_LIVE_DEV
+
+When using C<Apache::Test> during the project development phase, it's
+often convenient to have the I<project/lib> (live) directory appearing
+first in C<@INC> so any changes to the Perl modules, residing in it,
+immediately affect the server, without a need to rerun C<make> to
+update I<blib/lib>. When the environment variable
+C<APACHE_TEST_LIVE_DEV> is set to a true value during the
+configuration phase (C<t/TEST -config>, C<Apache::Test> will
+automatically unshift the I<project/lib> directory into C<@INC>, via
+the autogenerated I<t/conf/modperl_inc.pl> file.
+
+
+=head1 Special Placeholders
+
+When generating configuration files from the I<*.in> templates,
+special placeholder variables get substituted. To embed a placeholder
+use the C<@foo@> syntax. For example in I<extra.conf.in> you can
+write:
+
+ Include @ServerRoot@/conf/myconfig.conf
+
+When I<extra.conf> is generated, C<@ServerRoot@> will get replaced
+with the location of the server root.
+
+Placeholders are case-insensitive.
+
+Available placeholders:
+
+=head2 Configuration Options
+
+All configuration variables that can be passed to C<t/TEST>, such as
+C<MaxClients>, C<DocumentRoot>, C<ServerRoot>, etc. To see the
+complete list run:
+
+ % t/TEST --help
+
+and you will find them in the C<configuration options> sections.
+
+=head2 NextAvailablePort
+
+Every time this placeholder is encountered it'll be replaced with the
+next available port. This is very useful if you need to allocate a
+special port, but not hardcode it. Later when running:
+
+ % t/TEST -port=select
+
+it's possible to run several concurrent test suites on the same
+machine, w/o having port collisions.
