what does [[-aAdejflm]] mean?
Those are options which are explained in the man page
EXAMPLE:
Code:
The following options can be used with ps:

  -a  Prints information to standard output about all processes, except the
      session leaders and processes not associated with a terminal.

  -A  Writes information for all processes.

  -d  Prints information to standard output about all processes, except the
      session leaders.

Specifiers are explained in the ps man page
EXAMPLE:
Code:
Format Specifiers


  The following list contains all format specifiers that can be used with ps:

  Specifier   Header	Meaning
  ________________________________________________________________
  acflag      ACFLG

			[Tru64 UNIX]  Process accounting flag
  args	      COMMAND	Command arguments
  c	      C		CPU utilization factor for scheduling


what does [=header mean] ?
RTM - it should be apparent by now....

Quote:
what does [-g glist] mean?
what does [-u ulist] mean?
From the ps man page:

Prints only information about processes that are in the process groups
listed in glist. The glist is a list of process-group identifiers
enclosed in " " (double quotes) and separated from one another by a
comma or one or more spaces (or tabs), or both.


The ulist argument is either a list of
user IDs or a list of user IDs enclosed in " " (double quotes) and
separated from one another by a comma or one or more spaces, or both.

You should really try reading the complete man page and then ask questions about it - all of the descriptions are in the man page (in this case).

dh_installmanpages

DH_INSTALLMANPAGES(1)						     Debhelper						     DH_INSTALLMANPAGES(1)

NAME

       dh_installmanpages - old-style man page installer (deprecated)

SYNOPSIS

       dh_installmanpages [debhelperoptions] [file...]

DESCRIPTION

       dh_installmanpages is a debhelper program that is responsible for automatically installing man pages into usr/share/man/ in package build
       directories.

       This is a DWIM-style program, with an interface unlike the rest of debhelper. It is deprecated, and you are encouraged to use
       dh_installman(1) instead.

       dh_installmanpages scans the current directory and all subdirectories for filenames that look like man pages. (Note that only real files
       are looked at; symlinks are ignored.) It uses file(1) to verify that the files are in the correct format. Then, based on the files'
       extensions, it installs them into the correct man directory.

       All filenames specified as parameters will be skipped by dh_installmanpages.  This is useful if by default it installs some man pages that
       you do not want to be installed.

       After the man page installation step, dh_installmanpages will check to see if any of the man pages are .so links. If so, it changes them to
       symlinks.

OPTIONS

       file ...
	   Do not install these files as man pages, even if they look like valid man pages.

BUGS

       dh_installmanpages will install the man pages it finds into all packages you tell it to act on, since it can't tell what package the man
       pages belong in. This is almost never what you really want (use -p to work around this, or use the much better dh_installman(1) program
       instead).

       Files ending in .man will be ignored.

       Files specified as parameters that contain spaces in their filenames will not be processed properly.

       This program is a part of debhelper.
