'''BOO''' is a binary-to-text encoding originally associated with the ''Kermit'' communications software. The name is derived from the word &amp;quot;bootstrap&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
== Format details ==&lt;br /&gt;
The first line of a BOO file contains just the original filename.&lt;br /&gt;
&lt;br /&gt;
BOO is generally a base-64 encoding, using ASCII characters from '0' (48) to 'o' (111). It has a special way to encode a run of all-NUL bytes, using codes beginning with a '~' character.&lt;br /&gt;
&lt;br /&gt;
== Specifications ==&lt;br /&gt;
In some Kermit distributions, the format is described in a file named ckboo.hlp or ckboo.txt.&lt;br /&gt;
