DESCRIPTION
       This program merges the fields -- not the rows -- of delimited text
       files.  That is, if several files are almost but not quite entirely
       unlike each other in their structure (in their field names, numbers or
       orders), this script allows you to easily unify the files into one file
       with all the same fields.  The output can be based on fields as
       determined by the three "action" flags.

       For the following examples, consider three files that contain the
       following fields:

         +------------+---------------------------------+
         | File       | Fields                          |
         +------------+---------------------------------+
         | merge1.tab | name, type, position            |
         | merge2.tab | name, type, position, lod_score |
         | merge3.tab | name, position                  |
         +------------+---------------------------------+

       To list all available fields in the files and the number of times they
       are present:

         $ tabmerge --list merge*
         +-----------+-------------------+
         | Field     | No. Times Present |
         +-----------+-------------------+
         | lod_score | 1                 |
         | name      | 3                 |
         | position  | 3                 |
         | type      | 2                 |
         +-----------+-------------------+

       To merge the files on the minimum overlapping fields:

         $ tabmerge merge*
         +----------+----------+
         | name     | position |
         +----------+----------+
         | RM104    | 2.30     |
         | RM105    | 4.5      |
         | TX5509   | 10.4     |
         | UU189    | 19.0     |
         | Xpsm122  | 3.3      |
         | Xpsr9556 | 4.5      |
         | DRTL     | 2.30     |
         | ALTX     | 4.5      |
         | DWRF     | 10.4     |
         +----------+----------+

       To merge the files and include all the fields:

         $ tabmerge --max merge*
         +-----------+----------+----------+--------+
         | lod_score | name     | position | type   |
         +-----------+----------+----------+--------+
         |           | RM104    | 2.30     | RFLP   |
         |           | RM105    | 4.5      | RFLP   |
         |           | TX5509   | 10.4     | AFLP   |
         | 2.4       | UU189    | 19.0     | SSR    |
         | 1.2       | Xpsm122  | 3.3      | Marker |
         | 1.2       | Xpsr9556 | 4.5      | Marker |
         |           | DRTL     | 2.30     |        |
         |           | ALTX     | 4.5      |        |
         |           | DWRF     | 10.4     |        |
         +-----------+----------+----------+--------+

       To merge and extract just the "name" and "type" fields:

         $ tabmerge -f name,type merge*
         +----------+--------+
         | name     | type   |
         +----------+--------+
         | RM104    | RFLP   |
         | RM105    | RFLP   |
         | TX5509   | AFLP   |
         | UU189    | SSR    |
         | Xpsm122  | Marker |
         | Xpsr9556 | Marker |
         | DRTL     |        |
         | ALTX     |        |
         | DWRF     |        |
         +----------+--------+

       To merge the files on just the "name" and "lod_score" fields and sort
       on the name:

         $ tabmerge -f name,lod_score -s name merge*
         +----------+-----------+
         | name     | lod_score |
         +----------+-----------+
         | ALTX     |           |
         | DRTL     |           |
         | DWRF     |           |
         | RM104    |           |
         | RM105    |           |
         | TX5509   |           |
         | UU189    | 2.4       |
         | Xpsm122  | 1.2       |
         | Xpsr9556 | 1.2       |
         +----------+-----------+

       To do the same but mimic the original tab-delimited input:

         $ tabmerge -f name,lod_score -s name --stdout merge*
         name    lod_score
         ALTX
         DRTL
         DWRF
         RM104
         RM105
         TX5509
         UU189   2.4
         Xpsm122 1.2
         Xpsr9556        1.2

       Why would you want to do this?  Suppose you have several delimited text
       files with nearly the same structure and want to create just one file
       from them, but the fields may be in a different order in each file
       and/or some files may contain more or fewer fields than others.  (As
       far-fetched as it may seem, it happens to the author more than he'd
       like.)
