54 This part of the tutorial provides supporting information relevant to
55 the Catalyst tutorial.
57 =head1 APPENDIX 1: CUT AND PASTE FOR POD-BASED EXAMPLES
59 You may notice that Pod indents example code with four spaces. This
60 section provides some quick advice to "un-indent" this text in common
63 =head2 "Un-indenting" with Vi/Vim
65 When cutting and pasting multi-line text from Pod-based documents, the
66 following vi/vim regexs can be helpful to "un-indent" the inserted text
67 (do NOT type the quotes, they are only included to show spaces in the
68 regex patterns). I<Note that all 3 of the regexs end in 4 spaces>:
76 Removes four leading spaces from the entire file (from the first line,
77 C<0>, to the last line, C<$>).
83 A shortcut for the previous item (C<%> specifies the entire file; so
84 this removes four leading spaces from every line).
90 Removes the first four spaces from the line the cursor is on at the time
91 the regex command is executed (".") to the last line of the file.
97 Removes four leading space from the current line through line 44
98 (obviously adjust the C<44> to the appropriate value in your example).

106 =head1 APPENDIX 2: USING MYSQL AND POSTGRESQL
108 The main database used in this tutorial is the very simple yet powerful
109 SQLite. This section provides information that can be used to "convert"
110 the tutorial to use MySQL and PostgreSQL. However, note that part of
111 the beauty of the MVC architecture is that very little database-specific
112 code is spread throughout the system (at least when MVC is "done
113 right"). Consequently, converting from one database to another is
114 relatively painless with most Catalyst applications. In general, you
115 just need to adapt the schema definition C<.sql> file you use to
116 initialize your database and adjust a few configuration parameters.
118 Also note that the purpose of the data definition statements for this
119 section are not designed to take maximum advantage of the various
120 features in each database for issues such as referential integrity and
121 field types/constraints.
132 =head1 APPENDIX 3: IMPROVED HASHING SCRIPT
134 Here is an improved SHA-1 hashing script from Gavin Henry that does
135 not expose the passwords to "capture" on the command line.

181 . $sha1_enc->hexdigest . "\n"
182 . "Paste this into your SQL INSERT/COPY Data.\n";
185 print "\nPasswords do not match!\n";
