# NAME

podselect - function to extract selected sections of pod documentation

# SYNOPSIS

        use PDL::Pod::Select;
        podselect (@filelist);
        podselect ({OUTPUT => "tmp.out"}, @filelist):
        podselect ({SELECT => ["NAME|SYNOPSIS", "OPTIONS"]}, @filelist):
        podselect ({OUTPUT => ">&STDERR", SELECT => ["DESCRIPTION"]}, "-");

# DESCRIPTION

podselect() is a function which will extract specified sections of pod documentation from an input stream. This ability is already provided in the PDL::Pod::Parser module. Subclasses of PDL::Pod::Parser that wish to take advantage of this feature do not need to derive from PDL::Pod::Select. PDL::Pod::Select merely provides a single function named podselect() which provides this capability in function form (as opposed to object form) for extracting the raw pod docs.

## podselect(\%options, @filelist)

podselect will print the raw (untranslated) pod documentation of all pod sections in the given input files specified by `@filelist` according to the given options.

If any argument to podselect is a reference to a hash (associative array) then the values with the following keys are processed as follows:

`OUTPUT`
  A string corresponding to the desired output file (or ``>&STDOUT'' or ``>&STDERR''). The default is to use standard output.

`SELECT`
  A reference to an array of sections specifications (as described in SECTION SPECIFICATIONS in the PDL::Pod::Parser manpage) which indicate the desired set of pod sections and subsections to be selected from input. If no section specifications are given, then all sections of pod documentation are used.

All other arguments should correspond to the names of input files containing pod documentation. A file name of ``-'' or ``<&STDIN'' will be interpeted to mean standard input (which is the default if no filenames are given).
