NAME

       "LaTeXML::Util::Pathname"  - portable pathname and file-system utilities

DESCRIPTION

       This module combines the functionality File::Spec and File::Basename to give a consistent
       set of filename utilities for LaTeXML.  A pathname is represented by a simple string.

   Pathname Manipulations
       "$path = pathname_make(%peices);"
           Constructs a pathname from the keywords in pieces
             dir   : directory
             name  : the filename (possibly with extension)
             type  : the filename extension

       "($dir,$name,$type) = pathname_split($path);"
           Splits the pathname $path into the components: directory, name and type.

       "$path = pathname_canonical($path);"
           Canonicallizes the pathname $path by simplifying repeated slashes, dots representing
           the current or parent directory, etc.

       "$dir = pathname_directory($path);"
           Returns the directory component of the pathname $path.

       "$name = pathname_name($path);"
           Returns the name component of the pathname $path.

       "$type = pathname_type($path);"
           Returns the type component of the pathname $path.

       "$path = pathname_concat($dir,$file);"
           Returns the pathname resulting from concatenating the directory $dir and filename
           $file.

       "$boole = pathname_is_absolute($path);"
           Returns whether the pathname $path appears to be an absolute pathname.

       "$boole = pathname_is_url($path);"
           Returns whether the pathname $path appears to be a url, rather than local file.

       "$rel = pathname_is_contained($path,$base);"
           Checks whether $path is underneath the directory $base; if so it returns the pathname
           $path relative to $base; otherwise returns undef.

       "$path = pathname_relative($path,$base);"
           If $path is an absolute, non-URL pathname, returns the pathname relative to the
           directory $base, otherwise simply returns the canonical form of $path.

       "$path = pathname_absolute($path,$base);"
           Returns the absolute pathname resulting from interpretting $path relative to the
           directory $base.  If $path is already absolute, it is returned unchanged.

   File System Operations
       "$modtime = pathname_timestamp($path);"
           Returns the modification time of the file named by $path, or undef if the file does
           not exist.

       "$path = pathname_cwd();"
           Returns the current working directory.

       "$dir = pathname_mkdir($dir);"
           Creates the directory $dir and all missing ancestors.  It returns $dir if successful,
           else undef.

       "$dest = pathname_copy($source,$dest);"
           Copies the file $source to $dest if needed; ie. if $dest is missing or older than
           $source.  It preserves the timestamp of $source.

       "$path = pathname_find($name,%options);"
           Finds the first file named $name that exists and that matches the specification in the
           keywords %options.  An absolute pathname is returned.

           If $name is not already an absolute pathname, then the option "paths" determines
           directories to recursively search.  It should be a list of pathnames, any relative
           paths are interpreted relative to the current directory.  If "paths" is omitted, then
           the current directory is searched.

           If the option "installation_subdir" is given, it indicates, in addition to the above,
           a directory relative to the LaTeXML installation directory to search.  This allows
           files included with the distribution to be found.

           The "types" option specifies a list of filetypes to search for.  If not supplied, then
           the filename must match exactly.  The type "*" matches any extension.

       "@paths = pathname_findall($name,%options);"
           Like "pathname_find", but returns all matching (absolute) paths that exist.
