 ### Vertical Metrics Modifications
 
-font-line supports automated line spacing modifications to a user-defined percentage of the units per em metric.  This value will be abbreviated as UPM below.

 Increase or decrease the integer value to increase or decrease your line spacing accordingly.
 
-The original font file is preserved in an unmodified version and the modified file write takes place on a new path defined as `[original filename]-linegap[percent].[ttf|otf]`.  The path to the file is reported to you in the standard output after the modification is completed.  font-line does not modify the glyph set or hints applied to the font.  See the Details section below for a description of the OpenType table modifications that occur when the application is used on a font file.

 You can inspect the vertical metrics in the new font file with the `report` sub-command (see Usage above).
 
 #### Details of Font Metrics Changes with `percent` Sub-Command
 
-The interpretation and display of these multiple vertical metrics values is platform and application dependent.  [There is no broadly accepted "best" approach](https://github.com/source-foundry/font-line/issues/2).  As such, font-line attempts to preserve the original metrics design in the font when modifications are made with the `percent` sub-command.

 ### Important
 
-The newly defined vertical metrics values can lead to clipping of glyph components if not properly defined.  There are no tests in font-line to provide assurance that this does not occur. We assume that the user is versed in these issues before use of the application and leave this testing to the designer / user before the modified fonts are used in a production setting.
