.PP
When in doubt, default to whatever Damian Conway's \fIPerl Best
Practices\fR says.

\fIPrivate documentation\fR
.IX Subsection "Private documentation"
.PP
When documenting a private method, or providing documentation which is
not useful to the user of the module (and is presumably useful to the
developer), wrap it in =begin/end private.  This way it does not show
up in perldoc where a user would see it and yet is still available and
well formatted (that is, not just a lump comment) when looking at the
code.

\&  Called by L<Test::More>\*(Aqs C<import> code when L<Jifty::Test> is first
\&  C<use>\*(Aqd, it calls L</setup>, and asks Test::More to export its

\fITest temp files\fR
.IX Subsection "Test temp files"
.PP
Files created by tests should be declared as such using
Jifty::Test\->\fItest_file()\fR so they are cleaned up on a successful test
run.
.PP
\fIUse Shell::Command\fR
.IX Subsection "Use Shell::Command"
.PP
Shell::Command has a number of functions which work like common shell
file commands such as \f(CW\*(C`touch\*(C'\fR, \f(CW\*(C`cp\*(C'\fR and \f(CW\*(C`mv\*(C'\fR.  They are battle tested and
cross-platform.  Use them instead of coding your own.
.PP
For example, instead of this:
.PP
.Vb 2
\&    open my $file, ">foo";
\&    close $file;
.Ve
.PP
Do this:
.PP
.Vb 2
\&    use Shell::Command;
\&    touch $file;
.Ve
.PP
\fICase insensitive matching\fR
.IX Subsection "Case insensitive matching"
.PP
To check if a string equals another string case insensitively, do this
.PP
.Vb 2
\&    lc $foo eq lc $bar;
\&    lc $foo eq \*(Aqbar\*(Aq;
.Ve
.PP
not this:
.PP
.Vb 2
\&    $foo =~ /^\eQ$bar\eE/i;
\&    $foo =~ /^bar$/i;
.Ve
