.SH SYNOPSIS
.sp
\fBautodep\fP [options] <command>
.SH DESCRIPTION
.sp
Auto dependency builder is a tool for analysis files accessed during
building a package. It also can be used for runtime dependencies analysis.
.sp
The tool can block an access to files of defined packages.

Notes
.IP [1] 5
.
Fuse file system is slower than normal one. Program reads many files
while launching, so this will take more time than usual.
.IP [2] 5
.
Loading of dynamic libraries and direct syscalls will not be logged.
.SH EXAMPLES
.SS Get the potential dependencies of a xchat package:
.sp
autodep emerge xchat
.SS Get the potential dependencies of a xchat package, blocking x11\-misc/util\-macros package:
.sp
autodep emerge \-\-block x11\-misc/util\-macros emerge xchat
.SS Get the potential dependencies of a xchat package, and show files accessed:
.sp
autodep \-\-files emerge xchat
.SS Get the runtime dependencies of a xchat and show files accessed:
.sp
autodep \-\-fusefs \-\-files xchat
