PDFSaM or ''PDF Split and Merge'' software is a free and open source cross-platform set of tools for manipulating PDF documents. PDFSaM basically provides a command-line and graphical user interfaces to the iText library. The command-line interface is written in Java and dual-licensed under the GPLv2 and LGPLv2. In graphical mode there is a separate utility for each kind of task; these utilities serve as plugins to the main GUI and call the command-line tool for doing the actual work. The main GUI and its plugins are written in Java Swing and licensed solely under the GPLv2. Thus PDFSaM needs just a working Java Virtual Machine installed in the operating system in order to run. == The distribution system == PDFSaM comes in two different versions, both open sourced. The basic version is a simple desktop utility for the most common PDF manipulating tasks. It is freely accessible from the project's page both as source and compiled code. There are ''MSI packages'' for 32-bit and 64-bit MS Windows, ''.dmg'' for Mac OS X and ''ZIP bundle'' for the power users' convenience. ZIP bundle comes especially handy for use on the GNU/Linux platform: only a few GNU/Linux distributions have a PDFSaM package in their repositories, namely Debian,〔Debian repository (''PDFSaM'' package ).〕 Ubuntu〔Ubuntu repository (''PDFSaM'' package ).〕 and Arch Linux〔Arch Linux repository (''PDFSaM'' package ).〕 (as for April 2013). The enhanced version is actually the full version of the program, including some experimental features. While its source code is available from the project's SourceForge page under the GPL, the author of the software do not openly distribute the enhanced version's ready-made packages. In order to set up a working environment one has to either compile this version from source, or make a donation to the project (thus gaining access to the support forum and the compiled packages of the enhanced version). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PDF Split and Merge」の詳細全文を読む スポンサード リンク
