+.SH SYNPOPSIS
+gpkg [-f] [-u] [-x] [-fl] [-ul] [-d] [-h] [-v]
+.SH DESCRIPTION
+gpkg is a program included with the Glacier package manager. Its purpose is to make changes to the local Glacier package index, a database listing all installed packages. gpkg performs functions such as merging, updating, and removing. It downloads a Glacier package, sources it, and runs the necessary functions. Afterwards, the package file is "indexed", where it can be queried by gquery(1).
+.SH OPTIONS

+.SH NAME
+syspkg \- make changes to the global Glacier package index
+.SH SYNOPSIS
+syspkg [-f] [-u] [-x] [-fl] [-ul] [-h] [-v]
+.SH DESCRIPTION
+syspkg is a program included with the Glacier package manager. Its purpose is to make changes to the global Glacier package index, unlike gpkg(8), which modifies the local index. syspkg should not be used regularly, as the global index is controlled by Git, meaning all changes will be overwritten during an update.

+.TP
+.BR \-u		\-\-update
+updates a merged package
+.TP
+.BR \-x		\-\-remove
