+a simple gemini server
+
+It supports:
+ * mime types
+ * directory listing
+ * chunked file transfer
+ * passes most gemini-diagnostics tests
+ * user-defined charset/lang meta attributes
+
+The script will create ssl certificate with CN=localhost
+If you wish change domain of ssl certificate: use DOMAIN variable
+before execution of SlackBuild script.
+
+ DOMAIN=slackbuilds.org ./gem.SlackBuild
+
+Is created 'gmi' directory as database in /var
+Certificates are saved in /var/gmi/tls path.
+Capsule content must be save in /var/gmi/capsule path.
+
+Overview:
+
+/var/gmi           [ root:root  | 755 ]
+├── capsule        [ root:users | 775 ]
+├── log            [ root:users | 664 ]
+└── tls            [ root:root  | 755 ]
+    ├── server.crt [ root:root  | 644 ]
+    └── server.key [ root:users | 640 ]
+
+* daemon: that SlackBuild package have script for /etc/rc.d
+
+NOTE: Here is already existent gem binary (package manager for Ruby),
+then create alias for gem (gemini server):
+
+ alias gem="/usr/sbin/gem"
+ alias gemd="(ba)sh /etc/rc.d/rc.gem" - /bin/sh already appoint for bash
+on Slackware.
+
+* run gem as regular user, preferably - security questions.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
