NAME

       merge-info, merge and unmerge GNU Info index files

SYNOPSIS

       merge-info        [OPTION ...] FILE FILE

DESCRIPTION

       merge-info can merge and unmerge the GNU Info index files named 'dir'. These files are
       usally created by install-info at install time of an application, or automatically
       generated by a mkinfodir script.

       If you are installing 2 packages at two different locations, two different 'dir' files are
       created. Eg.: One in

                 /stow/foo/usr/local/info/dir

       and one in

                 /stow/bar/usr/local/info/dir

       This is the common case if you are using a tool like xstow(1). merge-info can handle this
       and can merge both 'dir' files and creates a new 'dir' file.

USAGE

       merge-info [OPTION ...] FILE FILE

       Merge two files:

             merge-info /stow/foo/info/dir /stow/bar/info/dir

       Remove the content of a 'dir' file from another 'dir' file

              merge-info -u /stow/foo/info/dir /stow/bar/info/dir

OPTIONS

       -dl -debug-level INT
           Set's the debug level. An unsigned integer is accepted. The default value is 0.

       -h -help
           Shows a help screen.

       -V -Version
           Displays the verion number of the XStow package. merge-info is shipped with xstow(1).

       -u -unmerge
           Unmerge instead of merge. Note: It is not possible splitting up one 'dir' file into
           two. But removing the content of one 'dir' file from the other one is possible.

       -o -outfile
           Write the resulting 'dir' file not to stdout. Write it to a given file. Since merge-
           info does not open this outfile until all the merging or unmerging stuff is done it is
           allowed that the outfile is one the source files. eg.:

               merge-info -u foo/info/dir bar/info/dir -o foo/info/dir

       -d -duplicate
           Remove duplicate entries. When merging 2 files an entry can appear in more than one
           section. If you do not wan't this, use this option.

ENVIRONMENT VARIABLES

       XSTOW_DEBUG_LEVEL
           Same as the -debug-level option.
