I have modified the code snippet. That should be easy to understand.
Usually debug and release are two build modes. One is for debug purposes and the other is for release purpose. You can ignore that for now.

md
md(1) BSD General Commands Manual md(1)
NAME
md -- process raw dependency files produced by cpp -MD
SYNOPSIS
md [-d] [-f] [-m makefile] [-u makefile] [-o outputfile] [-v] [-x] [-D c|d|m|o|t|D]
DESCRIPTION
The md command basically does two things:
Process the raw dependency files produced by the cpp -MD option. There is one line in the file for every #include encountered, but there are
repeats and patterns like .../dir1/../dir2 that appear which should reduce to .../dir2. md canonicalizes and flushes repeats from the depen-
dency list. It also sorts the file names and "fills" them to a 78 character line.
md also updates the makefile directly with the dependency information, so the .d file can be thrown away (see d option). This is done to
save space. md assumes that dependency information in the makefile is sorted by .o file name and it procedes to merge in (add/or replace [as
appropriate]) the new dependency lines that it has generated. For time effeciency, md assumes that any .d files it is given that were cre-
ated before the creation date of the "makefile" were processed already. It ignores them unless the force flag [f] is given.
FLAG SUMMARY
-d delete the .d file after it is processed
-f force an update of the dependencies in the makefile even though the makefile is more recent than the .n file (This implies that md has
been run already.)
-m makefile specify the makefile to be upgraded. The defaults are makefile and then Makefile
-u makefile like -m above, but the file will be created if necessary
-o outputfile specify an output file for the dependencies other than a makefile
-v set the verbose flag
-x expunge old dependency info from makefile
-D c|d|m|o|t|D subswitch for debugging. can be followed by any of "c", "d", "m", "o", "t", "D" meaning:
c show file contents
d show new dependency crunching
m show generation of makefile
o show files being opened
t show time comparisons
D show very low level debugging
