API for Perl Modules for new infra
==================================

Module TLSRC
------------

Constructor:
	TLSRC->new;
	TLSRC->new( name => "foobar", shortdesc => "The foobar package", ...);

Input/Output
	$tlsrc->from_file("package.tlsrc");
	$tlsrc->writeout
		without arg to stdout
		with arg to filehandle

Read/Write functions (with argument set, without arg read)

	$tlsrc->name
	$tlsrc->category
	$tlsrc->shortdesc
	$tlsrc->longdesc
	$tlsrc->catalogue
	$tlsrc->srcpatterns
	$tlsrc->docpatterns
	$tlsrc->runpatterns
	$tlsrc->binpatterns
	$tlsrc->depends
	$tlsrc->executes

Generation function
	$tlp = $tlsrc->make_tlp($tltree);
		generates a TLP object from itself (a TLSRC obj) and
		a TLTREE object (see below)


Module TLP
----------

Package variables:
	&TLP->zipdir
		set/returns the default location for created zip files

Constructur:
	TLP->new;
	TLP->new( name => "foobar", ...);

Input/Output
	$tlp->from_file("package.tlp");
		reads from file, only one tlp allowed in file
	$tlp->from_fh($filehandle [, $multi] );
		reads from $filehandle
		if $multi is undefined (ie not given) then multiple tlp
		in the same file are treated as errors 
		if $multi is defined then returns after reading one
		tlp
		returns 1 if it found a tlp, otherwise 0
	$tlp->writeout
		without arg to stdout
		with arg to filehandle
	$tlp->writeout_simple
		for comparison with tpm/tlps, will go away

	$tlp->make_zip($tltree[,$destdir[,$zipname]]);
		creates a zip file of the tlp in $destdir (if not 
		defined then TLP->zipdir is used).
		The file name of the created zipfile is $zipname (if not
		present $tlp->name.zip)

		If the package contains "binfiles"; then zip files for 
		all archs containing binfiles are created, and the zipfile
		name is
			$zipname-$arch.zip

Utilities:
	$tlp->recompute_sizes($tltree)
		recomputes all the *size fields, see below
	$tlp->is_arch_dependent
		true if it contains bin files, otherwise false

Read/Write functions (with argument set, without arg read)

	$tlp->name
	$tlp->category
	$tlp->revision
	$tlp->shortdesc
	$tlp->longdesc
	$tlp->catalogue
		reads/returns scalar
	$tlp->srcfiles
	$tlp->srcsize
	$tlp->docfiles
	$tlp->docsize
	$tlp->runfiles
	$tlp->runsize
		*files reads/returns array of files
		*size reads/returns scalar
	$tlp->binfiles
	$tlp->binsize
		note that this gives/returns a HASH of architectures!!
	$tlp->depends
	$tlp->executes
		reads/returns array

	$tlp->add_srcfiles(@files)
		adds @files to the list of srcfiles
	$tlp->add_docfiles(@files)
		adds @files to the list of docfiles
	$tlp->add_runfiles(@files)
		adds @files to the list of runfiles

	$tlp->add_binfiles($arch,@files)
		adds @files to the list of binfiles for arch=$arch
	
	$tlp->add_files($type,@files)
		adds @files to the list of $type = (run|doc|src)files
		NOT FOR binfiles!


Module TLTREE
-------------
(this one is still quite hacky)

Constructor

	TLTREE->new;
	TLTREE->new( svnroot => "path/to/svn/managed/dir" );

Init functions

	$tltree->init_from_svn
		changes to svnroot, calls svn status -v and builds
		up all the necessary information
	$tltree->init_from_statusfile($file)
		does the same as init_from_svn, but from a pre-made
		output of svn status -v

Input/Ouput

	$tltree->print
		to stdout, more or less for hacking only not usefull

Pattern matching functions
	
	$ref = $tltree->get_matching_files($type,$pattern)
		for $type = bin
			returns a ref to a hash of keys = architectures
		otherwise
			returns a ref to an array
		(see specification)

Other functions

	$tltree->file_svn_lastrevision($file)
		returns the revision of the last change of file
		as given by svn status -v
		undef if file is not contained in $tltree

	$tltree->size_of($file)
		returns the size of $file, or undef if not in tree

	&$tlsrc->architectures
		sets/reads the list of architectures,
		predefined to ....


Module TLDB
-----------

Constructore

	TLDB->new;
	TLDB->new ( location => "path/to/tldb/file" );

Read/Write functions (with argument set, without arg read)

	$tldb->location

Input/Output

	$tldb->from_file($filename);
		reads a tldb file (tlp descriptions separated by newlines)
	
	$tldb->writeout
		without arg to stdout 
		with arg to filehandle

	$tldb->save
		saves to $self->location;

	$tldb->generate_packagelist
		outputs list of "package revision" for web delivery
		without arg to stdout
		with arg to filehandle

TLP interface

	$tldb->add_tlp($tlp)
		adds a TLP to the TLDB (or replaces an already present)

	$tlp = $tldb->get_package("packagename");
		returns undef if not installed
	
	$rev = $tldb->package_revision("packagename");
		returns undef if not installed, otherwise the
		revision of "packagename"
	

Package TLUtils
---------------

exported functions:
	sort_uniq(@list)
	push_uniq(\@list,@list)
	dirname($file)
	basename($file)
