-    <para>FreeBSD provides binary compatibility with several other
-      &unix; like operating systems, including Linux.  At this point,
-      you may be asking yourself why exactly, does
-      FreeBSD need to be able to run Linux binaries?  The answer to that
-      question is quite simple.  Many companies and developers develop
-      only for Linux, since it is the latest <quote>hot thing</quote> in
-      the computing world.  That leaves the rest of us FreeBSD users
-      bugging these same companies and developers to put out native
-      FreeBSD versions of their applications.  The problem is, that most
-      of these companies do not really realize how many people would use
-      their product if there were FreeBSD versions too, and most continue
-      to only develop for Linux.  So what is a FreeBSD user to do?  This
-      is where the Linux binary compatibility of FreeBSD comes into
-      play.</para>
+    <para>FreeBSD 有提供其他幾種 &unix; like 作業系統的 binary 相容性，其中包括了 Linux。
+      你可能會納悶：為什麼 FreeBSD 需要能夠執行 Linux 專用執行檔(binary)呢？答案很簡單，
+      許多公司、開發者只會 Linux 開發程式，因為這是目前資訊界 <quote>最熱門</quote> 的玩意。
+      這逼得許多 FreeBSD 使用者不得不去勸說這些人是否提供可直接在 FreeBSD 上執行的版本。
+      但問題是，大多數公司並不瞭解會有多少人會用 FreeBSD 版，因此他們仍只開發 Linux 版。
+      那麼 FreeBSD 使用者該怎麼辦呢？答案就是用 FreeBSD 所提供的 Linux binary 相容。</para>
 
-    <para>In a nutshell, the compatibility allows FreeBSD users to run
-      about 90% of all Linux applications without modification.  This
-      includes applications such as <application>&staroffice;</application>,
-      the Linux version of <application>&netscape;</application>,
-      <application>&adobe;&nbsp;&acrobat;</application>,
-      <application><trademark class="registered">RealPlayer</trademark></application>,
-      <application><trademark>VMware</trademark></application>,
-      <application>&oracle;</application>,
-      <application><trademark class="registered">WordPerfect</trademark></application>, <application>Doom</application>,
-      <application>Quake</application>, and more.  It is also reported
-      that in some situations, Linux binaries perform better on FreeBSD
-      than they do under Linux.</para>
+    <para>簡單來講，這種相容性可讓 FreeBSD 使用者直接執行約 90% 的 Linux 程式，而不必做任何修改。
+      這些包括了： <application>&staroffice;</application>、
+      <application>&netscape;</application> 的 Linux 版、
+      <application>&adobe;&nbsp;&acrobat;</application>、
+      <application><trademark class="registered">RealPlayer</trademark></application>、
+      <application><trademark>VMware</trademark></application>、
+      <application>&oracle;</application>、
+      <application><trademark class="registered">WordPerfect</trademark></application>、<application>Doom</application>、
+      <application>Quake</application> 等等。此外，也有人回報說在某些情況下，
+      這些在 FreeBSD 上執行的 Linux 程式，甚至比原本在 Linux 執行得更好。</para>
 
-    <para>There are, however, some Linux-specific operating system
-      features that are not supported under FreeBSD.  Linux binaries will
-      not work on FreeBSD if they overly use &i386; specific
-      calls, such as enabling virtual 8086 mode.</para>
+    <para>然而呢，還是有些只限 Linux 特定的作業系統功能，在 FreeBSD 上並未支援。
+      如果 Linux 程式過於濫用只有 &i386; 架構上才能用的功能，比如：虛擬 8086 模式，
+      則可能無法在 FreeBSD 運作正常。</para>
