.SH NAME
Pod::Html::Util \- helper functions for Pod\-Html
.SH SUBROUTINES
.IX Header "SUBROUTINES"
\&\fBNote:\fR While these functions are importable on request from
\&\fIPod::Html::Util\fR, they are specifically intended for use within (a) the
\&\fIPod-Html\fR distribution (modules and test programs) shipped as part of the
Perl 5 core and (b) other parts of the core such as the \fIinstallhtml\fR
program.  These functions may be modified or relocated within the core
distribution \-\- or removed entirely therefrom \-\- as the core's needs evolve.
Hence, you should not rely on these functions in situations other than those
just described.
.ie n .SS process_command_line()
.el .SS \f(CWprocess_command_line()\fP
.IX Subsection "process_command_line()"
Process command-line switches (options).  Returns a reference to a hash.  Will
provide usage message if \f(CW\*(C`\-\-help\*(C'\fR switch is present or if parameters are
invalid.
.PP
Calling this subroutine may modify \f(CW@ARGV\fR.
.ie n .SS usage()
.el .SS \f(CWusage()\fP
.IX Subsection "usage()"
Display customary Pod::Html usage information on STDERR.
.ie n .SS unixify()
.el .SS \f(CWunixify()\fP
.IX Subsection "unixify()"
Ensure that \fIPod::Html\fR's internals and tests handle paths consistently
across Unix, Windows and VMS.
.ie n .SS relativize_url()
.el .SS \f(CWrelativize_url()\fP
.IX Subsection "relativize_url()"
Convert an absolute URL to one relative to a base URL.
Assumes both end in a filename.
.ie n .SS html_escape()
.el .SS \f(CWhtml_escape()\fP
.IX Subsection "html_escape()"
Make text safe for HTML.
.ie n .SS htmlify()
.el .SS \f(CWhtmlify()\fP
.IX Subsection "htmlify()"
.Vb 1
\&    htmlify($heading);
.Ve
.PP
Converts a pod section specification to a suitable section specification
for HTML. Note that we keep spaces and special characters except
\&\f(CW\*(C`", ?\*(C'\fR (Netscape problem) and the hyphen (writer's problem...).
.ie n .SS anchorify()
.el .SS \f(CWanchorify()\fP
.IX Subsection "anchorify()"
.Vb 1
\&    anchorify(@heading);
.Ve
.PP
Similar to \f(CWhtmlify()\fR, but turns non-alphanumerics into underscores.  Note
that \f(CWanchorify()\fR is not exported by default.
.ie n .SS trim_leading_whitespace()
.el .SS \f(CWtrim_leading_whitespace()\fP
.IX Subsection "trim_leading_whitespace()"
Remove any level of indentation (spaces or tabs) from each code block
consistently.  Adapted from:
